A University of Southampton academic has received a major research grant to help him explore the limitations of quantum theory. Dr Hendrik Ulbricht, a Reader in Physics and Astronomy, has been awarded nearly £500,000 by the John Templeton Foundation in the US. Sir John Templeton, the late American millionaire, investor and philanthropist, created the Foundation to encourage scientists and students across the globe to explore fundamental, big questions in astronomy and cosmology...

Researchers Recreate Elusive Phenomenon With Artificial Nuclei
2013-03-08 12:03:34

DOE/Lawrence Berkeley National Laboratory The first experimental observation of a quantum mechanical phenomenon that was predicted nearly 70 years ago holds important implications for the future of graphene-based electronic devices. Working with microscopic artificial atomic nuclei fabricated on graphene, a collaboration of researchers led by scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley...

Quantum-Memory In Atoms

Vienna University of Technology Order tends towards disorder. This is also true for quantum states. Measurements at the Vienna University of Technology show that in quantum mechanics this transition can be quite different from what we experience in our daily lives. Ice cubes in a cocktail glass melt until an equilibrium state is reached in which the ice cubes are gone. After that, the geometric shape of the ice cubes is completely lost. The liquid does not contain any memory of their...

In an article published in the PNAS scientific journal, researchers from Aalto University and the VTT Technical Research Centre of Finland showed experimentally that vacuum has properties not previously observed. According to the laws of quantum mechanics, it is a state with abundant potentials. Vacuum contains momentarily appearing and disappearing virtual pairs, which can be converted into detectable light particles. The researchers conducted a mirror experiment to show that by changing...

Playing Quantum Tricks By Reversing Measurements
2013-02-15 14:02:48

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...

Ever since Austrian scientist Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using something called quantum theory to explain and understand the nature of waves and particles. But a new paper by physics professor Andreas Albrecht and graduate student Dan Phillips at the University of California, Davis, makes the case that these quantum fluctuations actually are responsible for the probability of all actions, with far-reaching implications for theories...

Transporting At The Speed Of Light Into The Quantum Internet
2013-02-04 10:01:14

AlphaGalileo Not only do optical fibers transmit information every day around the world at the speed of light, but they can also be harnessed for the transport of quantum information. In the current issue of Nature Photonics, a research team of Innsbruck physicists led by Rainer Blatt and Tracy Northup report how they have directly transferred the quantum information stored in an atom onto a particle of light. Such information could then be sent over optical fiber to a distant atom....

Recycling In The Quantum World Could Lead To Better Teleportation

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...

Spacetime More Like A Smooth Whiskey Than A Foamy Brew
2013-01-11 04:58:51

April Flowers for redOrbit.com - Your Universe Online According to new research led by Michigan Technological University, spacetime might be less like a foamy beer and more like a smooth Einsteinian whiskey. Robert Nemiroff and his team studied the tracings of three photons of differing wavelengths to reach this heady conclusion. NASA's Fermi Gamma-ray Space Telescope recorded these tracings in 2009. About 7 billion light years from Earth, a gamma ray outburst threw the photons from...

Quantum Object Behavior Depends On Measurement Apparatus Used
2013-01-09 14:54:07

University of Vienna Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus used for observing the system, and therefore on the type of measurement performed. Anton Zeilinger's team of physicists at the University of Vienna and the Austrian Academy of Sciences has recently taken this phenomenon further than ever. Whether a certain photon behaves like a particle or like a wave depends on...

Niels Henrik David Bohr (October 7, 1885 - November 18, 1962) was a Danish physicist. He made essential contributions to understanding atom structure and quantum mechanics. Born in Copenhagen, Denmark to Christian Bohr and Ellen Adler, Bohr got his doctorate at Copenhagen University in 1911. He then studied under Ernest Rutherford in Manchester, England. Based on Rutherford's theories, Bohr published his Bohr model about atom structure in 1913, introducing the theory of electrons...
