Scientists and engineers have proven the worth of quantum cryptography in telecommunication networks by demonstrating its long-term effectiveness in a real-time network...

Researchers at the University of Pittsburgh have made advances in better understanding correlated quantum matter that could change technology as we know it, according to a study published in the Nov. 20 edition of Nature...

Wine drinkers know that swirling a good vintage around in a glass aerates the wine and releases its bouquet. Just how the process - known as 'orbital shaking' - works, however, has been something of a mystery...

Scientists at Chalmers University of Technology have succeeded in creating light from vacuum - observing an effect first predicted over 40 years ago. The results were published in the journal Nature. In an innovative experiment, the scientists have managed to capture some of the photons that are constantly appearing and disappearing in the vacuum...

The term entanglement was introduced by the Austrian Nobel laureate Erwin Schroedinger in 1935, and it describes a quantum mechanical phenomenon that while it can clearly be demonstrated experimentally, is not understood completely. Entangled particles cannot be defined as single particles with defined states but rather as a whole system. By entangling single quantum bits, a quantum computer will solve problems considerably faster than conventional computers. 'It becomes even more difficult to understand entanglement when there are more than two particles involved,' says Thomas Monz, junior scientist in the research group led by Rainer Blatt at the Institute for Experimental Physics at the University of Innsbruck. 'And now our experiment with many particles provides us with new insights into this phenomenon,' adds Blatt...

Shortly after experiments on the Large Hadron Collider (LHC) at the CERN laboratory near Geneva, Switzerland began yielding scientific data last fall, a group of scientists led by a Syracuse University physicist became the first to observe the decays of a rare particle that was present right after the Big Bang. By studying this particle, scientists hope to solve the mystery of why the universe evolved with more matter than antimatter...

'The nation that controls magnetism will control the universe,' famed fictional detective Dick Tracy predicted back in 1935. Probably an overstatement, but there's little doubt the nation that leads the development of advanced magnetoelectronic or 'spintronic' devices is going to have a serious leg-up on its Information Age competition. A smaller, faster and cheaper way to store and transfer information is the spintronic grand prize and a key to winning this prize is understanding and controlling a multiferroic property known as 'spontaneous magnetisation'...

Scientists of the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck, Austria, have reached a milestone in the exploration of quantum gas mixtures. In an international first, the research group led by Rudolf Grimm and Florian Schreck has succeeded in producing controlled strong interactions between two fermionic elements - lithium-6 and potassium-40. This model system not only promises to provide new insights into solid-state physics but also shows intriguing analogies to the primordial substance right after the Big Bang...

Physicists at UCLA set out to design a better transistor and ended up discovering a new way to think about the structure of space...

A team of physicists in the United Kingdom has taken a giant step toward realising efficient single-photon sources, which are expected to enable much-coveted completely secure optical communications, also known as 'quantum cryptography.' The team presents its findings in Applied Physics Letters, a journal published by the American Institute of Physics...

Northwestern University researchers have developed a new switching device that takes quantum communication to a new level. The device is a practical step toward creating a network that takes advantage of the mysterious and powerful world of quantum mechanics...

Physicists at the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park, have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling. Their technique opens new possibilities for studying and better understanding fundamental physics and has potential applications to quantum computing, next-generation 'spintronics' devices and even 'atomtronic' devices built from ultracold atoms...
