Dear Editor,As the old saying goes, ‘A picture is worth a thousand words’. The image displayed on a local television channel and on a news website recently of a member of the Public Relations Department of the Mayor and Councillors of the City of Georgetown in a deep slumber, drooling and with his mouth hanging open during the course of a statutory meeting of that body speaks volumes of the lethargy of the administration.How is it possible in the midst of a meeting of that august body, presided over by no less a person than His Worship the Mayor, and attended by other ‘city mothers and fathers’, senior municipal officers and members of civil society, that an officer could nonchalantly fall asleep and only awaken after a rumpus broke out about the ineptitude of that very department to which he belonged.Was he that bored, blasé and uninterested in the proceedings that he thought it best to catch up on some ZZZZZZZs? Or was he sending a subtle message to the Councillors that the meeting was just really a complete waste of time.Why didn’t any of his colleagues wake him, or is sleeping at these meetings a norm? Will he be hauled over the coals for this indiscretion or will it just be treated as a point of jester? In some countries, Generals and a Vice Premier who were caught napping during public functions addressed by their leaders have faced dire consequences.But then again, this is City Hall, and you have about 10 senior functionaries who were fingered for grave acts of misconduct by a Commission of Inquiry but who continue on their merry way as though nothing has happened. Indeed they continue to make a mess of things at the Council and are ostensibly given a pat on the back.I would like to suggest that for their future statutory meetings that the chairs be removed and as is done in some municipalities in the far East, that the Councillors and the officers be made to stand for the duration of the meetings. This would result in shorter meetings, in everyone remaining awake and having less idle talk.The more things change at the City Council, the more they remain the same.Sincerely,Roseanne Rodgers

Share Facebook Twitter Google + LinkedIn Pinterest Ohio’s agribusiness community, agricultural cooperatives and students in The Ohio State University’s College of Food, Agricultural, and Environmental Sciences (CFAES) will have greater access to research, educational opportunities and technical expertise through a new, college-wide Center for Cooperatives.The center, with staff based at CFAES’s Ohio State University South Centers in Piketon, will have a faculty presence on the Columbus campus. It will integrate the college’s current activities and operations that support cooperative business development, will engage directly with long-established cooperatives, and will provide education both in the classroom and through CFAES’s Ohio State University Extension program and other outreach activities.“The CFAES Center for Cooperatives is expected to be comprehensive and bring together all three mission areas of the college — teaching, research and Extension,” said Tom Worley, OSU South Centers director. “We are pleased to be well positioned to serve the cooperatives community in Ohio through the combined faculty and staff resources of the center.”Worley will oversee the center, with Ani Katchova, associate professor and farm income enhancement chair in CFAES, leading its research programs. Hannah Scott, program manager at the South Centers, will lead the new center’s Extension and outreach activities.Programming for the center will occur within all major CFAES mission areas with a goal of extending knowledge to emerging and established agricultural cooperatives in Ohio and supporting rural economic development. The center will also provide future agricultural professionals with interdisciplinary training and research opportunities.About 40 guests including CFAES faculty, cooperative leaders, and state and federal government representatives attended a reception celebrating the new center Oct. 18 in Columbus. In addition, Debbie Rausch from the Ohio office of the U.S. Department of Agriculture’s Rural Development program announced that CFAES has been awarded a Rural Cooperative Development Grant totaling nearly $200,000 to improve rural areas of Ohio and West Virginia through the development of cooperatives and other mutually owned businesses.

Related Posts What it Takes to Build a Highly Secure FinTech … Andrej Kovacevic Role of Mobile App Analytics In-App Engagement AI: How it’s Impacting Surveillance Data Storage Tags:#AI#business#HR#saas#startups For today’s startups, there are several things required to succeed. The first and the most important thing is a great idea. The second and only marginally less important thing is an ability to operate efficiently and at speed. For that reason, no startup can ignore any approach or technology that saves them time and money if they hope to survive.That’s part of the reason that startups have been so quick to embrace robotic process automation (RPA) and artificial intelligence (AI). In truth, there is no end to the ways that startups can gain an advantage by turning to technology in their daily operations. One of those ways has to do with how startups find and hire the talent they need to thrive and grow. That’s because a growing cadre of companies now offers applicant tracking systems in a SaaS model it’s perfect for small, growing companies. Here’s a look at why an a SaaS company can be a game-changer for startups and what their options are.Why Use an Applicant Tracking System?Startups, more than any other stage of the company, rely on talented workers to build out new products and establish their markets. That makes building out a human resources (HR) department as close to a must-have as you will find for an average startup. At the same time, research reveals that as much as 70% of today’s 35-and-under workforce would prefer a job at a startup to an established company. That means the HR departments within startup businesses have their hands full with eager job applicants ready to join their cause.The problem, however, is that screening all those potential new hires takes time, and that costs money. If there’s anything most startups can ill afford, it’s spending significant portions of their operating budgets on anything other than building viable products and lines of business. Using a SaaS system makes it possible for a small, agile startup HR department to handle the torrent of applicants, each opening attracts and provides benefits including:Centralized Resume StorageProviding Searchable Talent DatabasesStatistical AnalysisGreater Hiring TransparencyAutomated Applicant Pre-ScreeningIn short, a SaaS can take care of the time-consuming work it takes to narrow down candidates for a position by reading and ranking applicant resumes with little to no intervention. Also, most resume builder services now format their output, expecting it to be read by HR, so it just makes sense to use one.Choosing the Right StartupAs mentioned earlier, there’s no shortage of SaaS and cloud-based systems aimed at startups and other small companies. It’s a growing and vibrant segment, filled with enough solutions to meet any startup’s needs. The major players include:1. Hire by GoogleFor years, Google has offered a small business software suite that aims to be a comprehensive solution to the needs of growing companies. It made sense, then, when they added Hire by Google to their G Suite business offering. The system provides users with a fully-integrated hiring solution that does everything they could need. Major features include:Posting openings on multiple job boards at onceAutomated online profile search to assemble candidate data (finds things like LinkedIn and GitHub profiles)Automated resume keyword highlightingSmart interview schedulingClick-to-call and automated contact loggingPut simply, Hire by Google automates much of the repetitive processes involved in hiring, and does it in a single neat, attractive interface. As a bonus, it’s a natural fit for any startup that uses the other G Suite solutions, since it’s fully integrated into Gmail and Google Calendar.2. Zoho RecruitAs a company, Zoho is known as the place to go for business software solutions aimed at small businesses. The Zoho Recruit platform has a SaaS solution for that same market segment. What makes Zoho Recruit such an attractive proposition is the fact that it provides all of the basic features a startup could need in an ATS, and it integrates with all of Zoho’s other small business management software. Best of all, the basic version comes free of charge for a single user managing one active job, making it a no-brainer for a startup just building out their HR staffing and processes. Major features include:Advanced candidate data searchCentralized job posting managementCentralized resume storageAutomatic resume parsingBuilt-in online career portal for job seekersLike Hire for Google, the main draw is the fact that Zoho has software solutions for everything a startup needs, and they all work together. Zoho Recruit is also one of the more affordable ATS solutions out there, so it will serve its purpose while not draining precious startup funds, too.3. GreenhouseOne of the things that startups often struggle with is how to build a workplace culture that prioritizes diversity and inclusion. That’s what the Greenhouse ATS solution aims to help with. It does so by being one of the most data-centric ATS systems available to the startup segment, including built-in analytics and reporting tools that are second to none. Better still, the Greenhouse software ecosystem is all about HR, so the platform also offers an onboarding component, CRM functionality, and tools purpose-built to root out unconscious bias and create consistent applicant evaluation processes. Major features include:Automated job postings on multiple job boards, as well as social media like Twitter, Facebook, and LinkedInAutomatic application screening with user-customized selection criteriaInterview scheduling and reminder systemsAdvanced analytics tools and reporting functionsTaken together, the Greenhouse ATS solution provides everything the modern startup needs to find candidates from all kinds of different backgrounds and to build a healthy workplace culture that will stand the test of time.4. Bullhorn Staffing and RecruitingEvery startup wants to become the next market unicorn. That means that no two startups are likely to do things the same way, or have the same needs in an ATS system. Bullhorn Staffing and Recruiting offers an ATS solution that covers all the standard bases – and has a robust third-party integration marketplace that aims to cover every outside-the-box use case imaginable. Major features include:Unlimited user interface customizationCompatibility with Salesforce automationAutomated candidate searchHuge list of available feature integrationsThe only major downside to the Bullhorn solution is that it is among the priciest options in the market. The high price tag does mean, however, that any startup that chooses this solution won’t ever outgrow it, because the endless customizations allow it to scale up to an enterprise-class solution that would be right at home in today’s biggest corporations.The Bottom LineAny of the above solutions would make an excellent addition to a startup’s HR arsenal. They all act as force-multipliers, allowing fewer HR staff to stay on top of endless floods of job applicants, and see to the voracious talent needs of a growing business. They all accomplish that without being cost-prohibitive, too. The bottom line is that in a world where startups live and die based on their ability to iterate, grow, and evolve efficiently, an ATS is a natural fit. And now that the SaaS market seems to be offering ATS solutions for all manner of startup needs, they should take advantage of it and make sure to stay ahead of the curve – and the competition.

What do you do when you have so many camera angles that the multi-camera monitor is no longer a viable option? Make sure you’re always choosing the best shot possible with this unconventional workaround in Premiere Pro.When working with projects such as single-camera music videos with performance footage and a narrative element, it’s easy to suddenly be dealing with something like thirty camera angles. At that point using the traditional multi-camera monitor may not be a viable solution, either because your computer can’t handle that many streams without the need of very low-resolution proxies or simply because keeping track of that many thumbnails is very difficult. The process explained in the video below could be the solution you’re looking for. (If you’re following the step-by-step walkthrough below the video, click on the images to enlarge them in a new tab.)1. Synchronize your footage in a new sequence with a separate track for each angle in the video.Whether it’s performance footage or a narrative storyline, the first step is very similar to a common approach to creating a traditional multi-camera workflow. As you can see in the image above, there’s a huge number of angles to deal with in this particular example.2. Color code groups of tracks that relate to each other so it will be easy to identify them later in the process.Right-click on each clip in the timeline and select Label to change its color. See the image above for an example.3. Use the Target Track feature to use this particular approach.Turn off the V1 Target Track by clicking the highlighted V1 to the left of Video Track 1. Create a new track at the top of all of your clips and name it Print Track. To target this track, make sure that you click on the V32 (or whatever number coincides with your number of tracks).This means that anything you paste or insert will go directly to this track. Since your Print Track is at the top of the order in your timeline, anything that appears on that track will be seen in the Program window.4. Use the Toggle Track buttons to the left of each clip to temporarily make a track viewable in the Program Monitor.Remember that whatever track is highest in the stack of tracks in your timeline will be viewable as long as the Track Output is enabled. So to see Video Track 1, for example, you would need to turn off each Track Output above it.5. Now that you’ve targeted the Print Track, anything you paste will appear anywhere the playhead is located. By using the razor blade (Quick Key: C), arrow (Quick Key: V), and the rolling edit tool (Quick Key: N) in conjunction with the copy and paste commands (Quick Keys: Command+C and Command+V), you can now begin selecting segments from any of your tracks.Additionally, you can use the up and down arrows to quickly snap the playhead to the beginning or ending of any clip located on the Print Track. This will be very useful when you can’t see the Print Track when choosing content from the lower tracks in your sequence. Pushing the up-arrow key moves backwards in time while the down-arrow key moves you forward in time.6. Choose your opening shot and let it play until you’re ready to switch to a different angle. Once the shot is complete, make a cut using the razor blade tool, switch to the arrow tool to select the clip, and hit the up arrow to return to the start of the sequence. (If your clip has empty space between it and 00:00:00:00, then position the playhead at the clip start for this first clip.) Next, hit Command +C to copy and Command +V to paste.You should now see a copy of the clip in the same point in time on the targeted Print Track. Continue in this manner until you’ve completed your edit.Results: Everything on the Print Track will now reflect your edits and will play back with ease even on a modest system. This method is time-consuming, but it can be a great solution once you’re able to use the quick-key commands without thinking. I’ve used this method in several scenarios:1. When there wasn’t disk space or time to make proxies of a very large project.2. When there were too many camera angles, and flipping between multiple pages in the multi-camera monitor was affecting my edit decisions.3. When my clients try to edit content for themselves on very modest systems that require so much compression in the proxies that they can no longer tell if the shot is in focus or generally useable.How do you go about editing multi-angle projects?

Two goals in two games, and both of them instinctive first-time finishes. It’s fair to say that Marcus Rashford enjoyed a productive international break with England, having had a disruptive start to the season with Manchester United.The 20-year-old returned a few days early from his delayed summer holiday after World Cup duty in order to fill out Jose Mourinho’s short-handed front line. His reward was a rare start in the centre of attack on opening night against Leicester City.But since that 66-minute outing Rashford has not started again at club level, and his outing at Burnley lasted just 10 minutes before he was sent off for a retaliatory head-butt on ex-Red Phil Bardsley . As a result he will sit out the trip to Watford on Saturday as he begins a three-match ban, although he will still be in contention for the visit to Young Boys which starts United’s Champions League campaign on Wednesday. Article continues below Editors’ Picks Man Utd ready to spend big on Sancho and Haaland in January Who is Marcus Thuram? Lilian’s son who is top of the Bundesliga with Borussia Monchengladbach Brazil, beware! Messi and Argentina out for revenge after Copa controversy Best player in MLS? Zlatan wasn’t even the best player in LA! Ahead of his absence at Vicarage Road, Rashford’s goals against Spain and Switzerland for the Three Lions have reopened conversation in some circles regarding his suitability to the role of central striker. Having partnered Harry Kane to reasonable effect in the UEFA Nations League game at Wembley, he also turned in a decent showing alongside Danny Welbeck against the Swiss in Leicester.Yet there were still signs that the attacker, who has spent much of his time under Mourinho at United in a platoon with Anthony Martial and latterly Alexis Sanchez for the starting left-wing spot, doesn’t quite have the predatory instincts in front of goal necessary to become a consideration in the No.9 spot currently occupied by Romelu Lukaku.While Rashford’s two-goal salvo against Liverpool last season and the game-winning performance he turned in against Chelsea the previous year have been two of the stand-out showings under Mourinho since his arrival as manager in 2016, the youngster still has to make far more of the opportunities that come his way if he is to command a place in the centre of attack going forward.He had two such chances late in the game against Spain, but England great Alan Shearer suggested it is his lack of starts as a true No.9 which have compromised his game .Writing in The Sun , Shearer asserted: “Unfortunately his two missed chances that could have earned England a point also told you where he is at right now.“A centre-forward who is playing regularly in that position for his club probably would not have fluffed those… He would put those chances away and believe in himself — you get a taste for it, it is a feeling you love.”In truth, though, this is not a new phenomenon for Rashford. While he burst onto the scene with those memorable doubles against Midtjylland and Arsenal in February 2016, he has been far from prolific since then and has been found wanting in key moments for club and country before now.When he failed to open the scoring with a header under pressure from Thibaut Courtois at a key moment in United’s 1-0 defeat at Chelsea last term, Gary Neville blasted on Sky Sports : “Marcus Rashford, you closed your eyes! You closed your eyes! Just don’t look at the goalkeeper and he scores.”And in the World Cup group clash with Belgium when he was given the chance to prove his worth, he somehow failed to hit the target from a sublime Jamie Vardy assist with only Courtois to beat.For the large part Rashford’s pace in the channels has been the most compelling asset in his game following that unforgettable arrival on the senior stage, but his finishing has not been nearly as sharp. Perhaps Shearer is right that a player who is being allowed to drift into scoring positions with more regularity would be more likely to find the net at a higher rate.But you have to make the chance for yourself at a club like Manchester United. Were Rashford at a lesser Premier League club there would be a far longer leash to play his way into certain habits, but United simply can’t give that licence over a lengthy period of time. And especially not at a time when the Red Devils are desperately trying to get back on their feet.With Lukaku having netted 27 goals last season, Rashford has a lot to live up to if he is to make Mourinho think about either replacing the Belgian or using the England star as a long-term partner in a reshaped forward line. His return of 28 goals in 124 appearances for United in the last two-and-a-half years does not jump from the page when it comes to strikers’ records, and some of his big-stage sitters have done little to support the cause.Rashford for now remains a player of huge potential, an attacker with explosive pace and excellent temperament on the ball, a worthy occupant of the United No.10 shirt worn by so many stars of the past. But he has still got a lot to prove if he is to become the figurehead of United’s attacks in the years to come.

Share your voice Online Sports Tags Google honors legendary big-wave surfer and lifeguard Eddie Aikau. Google Eddie Aikau was an iconic Hawaiian surfer as famous for his prowess on big waves as he was as a lifeguard who saved hundreds of lives from the dangerous surf of Oahu’s north shore.But it’s for his final rescue attempt that he’s beloved in the Hawaiian community. To honor the legendary surfer and lifeguard, Google dedicated an animated Doodle to Aikau on what would have been his 73rd birthday. For almost as long as Google has been around, it’s livened up its barebones search page with artwork that draws attention to notable people, events, holidays and anniversaries. Google Doodles have celebrated, among many other things, Pac-Man’s anniversary, Copernicus’ birthday, Mother’s Day and the World Cup, as well as reminding us of lesser-known real-world heroes. Aikau was one of those real-world heroes.Born in Maui on May 4, 1946, Aikau was a descendant of the high priest to King Kamehameha I. After his family moved to Oahu, he dropped out of school at the age of 16 to take a job at the Dole pineapple cannery; his paycheck allowed him to buy his first surfboard.In 1967, Aikau was hired as the first lifeguard at Waimea Bay on Oahu’s north shore, where waves frequently reach 30 feet or higher. He’s credited with saving more than 500 people during his brief career, never losing a soul on his watch.Aikau also made his mark as a big-wave surfer, riding every major swell to hit the north shore between 1967 and 1978. “Eddie was a pretty quiet guy, but when there was a challenge, or some risk to be taken, or a game to be played that everybody wanted to win, Eddie seemed to rise to the top,” his younger brother Clyde said in a profile published by surfboard maker Quiksilver. “He was high risk at an early age.” In pro surfing, Aikau reached a rank of 12th best in the world and won several surfing awards, including the 1977 Duke Kahanamoku Invitational Surfing Championship.In 1978, he was chosen to join the crew of a cultural expedition between Hawaii and Tahiti on the Polynesian voyaging canoe Hokulea. During the 30-day, 2,500-mile voyage, the double-hulled canoe developed a leak and capsized about 12 miles south of the island of Molokai.In an effort to get help for the crew, Aikua paddled off on his surfboard toward the island of Lanai. The crew was eventually rescued by the US Coast Guard, but Aikau was never seen again.In 1985, a big-wave surfing tournament called Quiksilver Big Wave Invitational in Memory of Eddie Aikau, aka The Eddie, was established at Waimea Bay to honor Aikau’s legacy. Before the competition can be held, the tournament’s rules require open-ocean swells must be at least 20 feet high, which generally generates wave faces in the bay of about 30 feet. As a result, the tournament has been held only nine times, most recently in 2016. Comments 2 Google Doodle
Share Richard Drew/APDonald Trump Jr. appears on Sean Hannity’s Fox News program on Tuesday to discuss his meeting with a Russian lawyer in 2016 after promises of getting damaging information about Hillary Clinton.Updated at 11:35 p.m. ETDonald Trump Jr. acknowledged in an interview with Fox News on Tuesday that “in retrospect, I probably would have done things a little differently” when meeting last year with a Kremlin-linked attorney in hopes of gaining damaging information on Hillary Clinton.In an interview with Fox News host Sean Hannity, President Trump’s eldest son explained that he met with attorney Natalia Veselnitskaya at the urging of publicist Rob Goldstone because he “wanted to hear it out” to see what type of details they had.“I had been reading about scandals that people were probably underreporting for a long time, so maybe it was something that had to do with one of those things,” Trump Jr. said.Goldstone described the information “that would incriminate” Clinton as “part of Russia and its government’s support for Mr. Trump.” He also described the woman Trump Jr. would later meet as a “Russian government attorney.” Asked whether any “sirens” went off for him, Trump Jr. said, “Honestly, I don’t know.” He added it was “pre-Russia fever” and “pre-Russia mania.”“So I don’t even think my sirens went up, or the antennas went up at this time, because it wasn’t the issue that it’s been made out to be over the last nine months, 10 months, since it really became a thing,” Trump Jr. said.He also characterized the meeting as a “courtesy” to Goldstone, a business acquaintance.“I didn’t know if there was any credibility, I didn’t know if there was anything behind it, I can’t vouch for the information. Someone sent me an email. I can’t help what someone sends me. I read it, I responded accordingly,” Trump Jr. told Hannity.The president’s son posted an email exchange about setting up the June 2016 meeting on Tuesday morning just before The New York Times, which initially broke the story of the meeting over the weekend, was about to publish the emails.Trump Jr. reiterated that he was willing to cooperate with congressional committees that are investigating Russia and possible collusion with the Trump campaign, and he told Hannity that would include testifying under oath.“I just want the truth to get out there,” Trump Jr. said. “And that’s part of why I released all the stuff today, I wanted to get it all out there.”Ultimately, the meeting — which was also attended by Trump’s then-campaign chairman Paul Manafort and his son-in-law Jared Kushner, who now serves as a White House senior adviser — was a bust, Trump Jr. said. He added that Kushner left the meeting after about five minutes and Manafort spent most of the meeting on his phone.“I wouldn’t have even remembered it until you started scouring through this stuff,” the president’s son said. “It was literally just a wasted 20 minutes, which was a shame.”Trump Jr. also said he never told his father about the meeting, because “there was nothing to tell.”As to whether he has ever held additional meetings with Russians, Trump Jr. said, “I don’t even know, I’ve probably met with other people from Russia … not in the context of actual, a formalized meeting or anything like that, because why would I?”In one of the June 2016 emails to Trump Jr., Goldstone said, “This is obviously very high level and sensitive information but is part of Russia and its government’s support for Mr. Trump.”Trump Jr. wrote back, “if it’s what you say I love it especially later in the summer.”Aside from the emails and meeting, Hannity focused much of his program on bashing the mainstream media, inviting Trump Jr. to do so as well.“They’re trying drag out the story, in all fairness,” the Trump son said. “They have it, they want to drip a little bit today, drip a little bit then; it’s like, here it is. I’m more than happy to be transparent about it, and I’m more than happy to cooperate with everyone.”As NPR’s Peter Overby and Marilyn Geewax note, the situation has put Trump Jr. in legal hot water because there is a federal law that says “foreign nationals cannot ‘directly or indirectly’ give a ‘thing of value’ to American political campaigns. Moreover, the law says no one is allowed to ‘solicit, accept, or receive’ any thing of value from a foreign national to help a candidate.”The White House stood behind Trump Jr. on Tuesday as the controversy was unfolding, with White House spokeswoman Sarah Sanders reading a statement from the president saying, “My son is a high-quality person and I applaud his transparency.” Ahead of the Hannity segment airing, Trump promoted the interview on his personal Twitter account, calling his son “a great person who loves our country!”Copyright 2017 NPR.

Explore further (PhysOrg.com) — By greatly amplifying one photon from an entangled photon pair, physicists have theoretically shown that human eyes can be used as detectors to observe quantum effects. Usually, detecting quantum phenomena requires sensitive photon detectors or similar technology, keeping the quantum world far removed from our everyday experience. By showing that it’s possible to perform quantum optics experiments with human eyes as detectors, the physicists can bring quantum phenomena closer to the macroscopic level and to everyday life. The group of physicists is from the University of Geneva, and includes Pavel Sekatski, Nicolas Brunner (also from the University of Bristol), Cyril Branciard, Nicolas Gisin, and Christoph Simon. In their study published in a recent issue of Physical Review Letters, the scientists theoretically show how human eyes can be used to detect a large Bell inequality violation, which proves the existence of quantum entanglement.As the physicists explain, the key to achieving human-eye detection of quantum effects is to use the process of quantum cloning by stimulated emission. Recently, using quantum cloning, researchers in Rome have experimentally created tens of thousands of clones starting from a single-photon. Then, by amplifying one photon of an entangled pair, the researchers managed to demonstrate entanglement. In order to do this, specific detectors are required, which can distinguish two orthogonal amplified states with a high success rate. Now, what Sekatski and co-workers have shown is that the human eye performs extremely well at the task of distinguishing between orthogonal amplified states. This is a consequence of the eye’s main characteristic, namely as a detection threshold. Below a certain threshold number of incoming photons, the eye remains blind (no light is seen), whereas above the threshold the efficiency (i.e. the probability of seeing) is close to one. In their calculations, the authors also considered the influence of experimental imperfections, such as photon losses, which are inevitable in a real experiment. They found that the setup is surprisingly robust. A strong Bell violation can be obtained even in case of high losses, demonstrating the presence of entanglement. This is a very astonishing feature since entanglement is generally an extremely fragile property, highly sensitive to experimental imperfections such as losses. To solve this apparent paradox, the scientists uncovered a loophole in the system. They showed that a specific multi-photon state could actually behave exactly as the entangled state. Therefore, the high Bell violation actually witnesses the entanglement of the original photon pair, i.e. before the amplification occurs, but not the entanglement between the amplified state and the single photon. Still, the authors show that the amplified state and the single photon are nevertheless entangled, but revealing this entanglement would require more sophisticated measurements. This subtle issue provides a much better understanding of the quantum nature of amplified states, which were recently the subject of a controversy among the scientific community.As the researchers finally note, using human eyes as detectors in actual quantum experiments will face significant technical challenges. However, the possibility of observing quantum effects directly with our own eyes is fascinating. Naked eye observation would bring the observer one step closer to the quantum world.“From our theoretical study, the experimental perspectives appear very promising,” Brunner told PhysOrg.com. He added that, although there will be many technical challenges, Nicolas Gisin’s research group in Geneva has already started working on experiments.More information: Pavel Sekatski, Nicolas Brunner, Cyril Branciard, Nicolas Gisin, and Christoph Simon. “Towards Quantum Experiments with Human Eyes as Detectors Based on Cloning via Stimulated Emission.” Physical Review Letters 103, 113601 (2009).Copyright 2009 PhysOrg.com.
