Latest Quantum entanglement Stories
Brett Smith for redOrbit.com - Your Universe Online As concerns over cyber security grow with each newly publicized attack, computer scientists have been pursuing quantum technology as a silver bullet against would-be hackers. According to a groundbreaking announcement, scientists at Los Alamos National Labs in New Mexico have been utilizing a small-scale “quantum internet” for the past two years. Quantum cryptography is possible because of the phenomenon known as quantum...
Synthetic Diamond Material Integral to Achieving Quantum Entanglement Between Atom-like Defects in Two Pieces of Diamond, Driving Advancements in Information Technologies and Fundamental Physics SAN FRANCISCO, May 3, 2013 /PRNewswire/ -- Element Six, the world leader in synthetic diamond supermaterials and member of the De Beers Group of Companies, today announced in collaboration with Delft University of Technology the entanglement of electron spin qubits (quantum bits) in two...
University of Vienna A team led by the Austrian physicist Anton Zeilinger has now carried out an experiment with photons, in which they have closed an important loophole. The researchers have thus provided the most complete experimental proof that the quantum world is in conflict with our everyday experience. The results of this study appear this week in the renowned journal Nature (Advance Online Publication/AOP). When we observe an object, we make a number of intuitive assumptions,...
April Flowers for redOrbit.com - Your Universe Online "Spooky action at a distance" is how Albert Einstein rather famously described the theory of quantum entanglement. Until now, however, experiments attempting to examine this peculiar quantum mechanical phenomenon have been limited to relatively small distances on Earth. Researchers have proposed a solution to this in a new study published in the New Journal of Physics. To test the limits of Einstein's "spooky action" and potentially...
Brett Smith for redOrbit.com - Your Universe Online Albert Einstein, almost unanimously considered the greatest physicist since Sir Isaac Newton, would have turned 134 today. His legacy can still be seen in modern society – in the revelations being made by physicists around the world and by his theories that they are still struggling to comprehend. "I am convinced that (God) does not play dice." Perhaps the most prominent contemporary example of Einstein’s legacy is the...
John P. Millis, Ph.D. for redOrbit.com – Your Universe Online Black holes are incredibly difficult objects to understand, partially because their very existence seemingly challenges the physical laws of the Universe. Because of their extreme nature, various peculiarities arise that give scientists pause. One such case was proposed by Stephen Hawking, the famed cosmologist, back in the 1970s. He noted that because of the extreme gravity that exists within the event horizon of a black...
University of Innsbruck A team of physicists at the University of Innsbruck, Austria, performed an experiment that seems to contradict the foundations of quantum theory – at first glance. The team led by Rainer Blatt reversed a quantum measurement in a prototype quantum information processor. The experiment is enabled by a technique that has been developed for quantum error correction in a future quantum computer. Measurements on quantum systems have puzzled generations of physicists...
Alan McStravick for redOrbit.com - Your Universe Online What Einstein once referred to as “spooky action at a distance” could be our way into a 'Star Trek' future Watching the original 'Star Trek' series as a child, the most enthralling part of any episode was the moment they dissolved during teleportation on their way down to an alien planet. The science behind that at-one-time fiction shows it is now en route to becoming fact. The possibility of teleportation was first...
While some theoretical physicists make predictions about astrophysics and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Such is the case at UC Santa Barbara, where theoretical physicists at the Kavli Institute for Theoretical Physics (KITP) cover the range of questions in physics. Recently, theoretical physicists at KITP have made important strides in studying a concept in quantum physics called quantum entanglement, in...
April Flowers for redOrbit.com - Your Universe Online A research team led by the University of Vienna has developed a new method for entangling single photons that gyrate in opposite directions. This is the first step towards entangling and twisting even macroscopic, spatially separated objects in two different directions, according to the team. The findings of this study have been published in the journal Science. Quantum physics is the theory of lightweight objects such as atoms or...
