Image 1 - Ultracold Experiments Heat Up Quantum Research
2012-03-21 04:17:04

University of Chicago physicists have experimentally demonstrated, for the first time, that atoms chilled to temperatures near absolute zero may behave like seemingly unrelated natural systems of vastly different scales, offering potential insights into links between the atomic realm and deep questions of cosmology. This ultracold state, called “quantum criticality,” hints at similarities between such diverse phenomena as the gravitational dynamics of black holes or the exotic...

Looking At Quantum Gravity In A Mirror
2012-03-21 04:10:14

Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale is so remote from current experimental capabilities that tests of quantum gravity are widely believed to be nearly impossible. Now an international collaboration between the groups of Caslav Brukner and Markus Aspelmeyer at the University of Vienna and Myungshik Kim at Imperial...

New technique could open the door to practical superconductor applications, as well as to solving difficult 'many-body' problems in high-energy physics, condensed matter and ultra-cold atoms Combining known factors in a new way, theoretical physicists Boris Svistunov and Nikolai Prokof'ev at the University of Massachusetts Amherst, with three alumni of their group, have solved an intractable 50-year-old problem: How to simulate strongly interacting quantum systems to allow accurate...

The Ever-expanding Hunt For The Elusive Higgs
2012-03-07 14:11:54

Scientists working at the US Tevatron particle collider near Batavia, Illinois on Wednesday said they have found the strongest evidence yet for the existence of the elusive “God particle.” They said their experiments mirror those from the Large Hadron Collider (LHC) in Europe that have narrowed the range where the Higgs boson particle could be hiding. The Higgs Boson is the missing link in the standard model of physics and is believed to be what gives objects mass, though...

Researchers at the UNIGE have succeeded in entangling 2 macroscopic crystals, a step towards the development of quantum memory For almost fifteen years Professor Nicolas Gisin and his physicist col- laborators have been entangling photons. If this exercise seems to them perhaps henceforth trivial, it continues to elude us ordinary humans. The laws that govern the quantum world are so strange that they completely escape us human beings confronted with the laws of the macroscopic world. This...

IBM Makes Strides In Quantum Computing Technology
2012-02-29 05:13:35

IBM revealed on Tuesday that it has achieved a major advance in quantum computing that will allow engineers to begin working on a full-scale quantum computer. The new breakthrough allows scientists to reduce data error rates in elementary computations while maintaining the integrity of quantum mechanical properties in quantum bits of data. Mark Ketchen, the manager of physics of information at the IBM's TJ Watson Research Center, said the creation of quantum computers would mean data...

One More Victory Scored Over Uncertainty In Quantum Physics Measurements
2012-02-27 05:56:47

Squeezing what hasn't been squeezed before Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider purchasing. For scientists, reducing uncertainty is a no less important goal, though in the weird realm of quantum physics, the term has a more specific meaning. For scientists working in quantum physics, the Heisenberg Uncertainty Principle says that...

Quantum cryptography is the ultimate secret message service. Now new research, to be presented at the 2012 AAAS Annual Meeting, shows it can counter even the ultimate paranoid scenario: when the equipment or even the operator is in the control of a malicious power. Until now, quantum cryptography protocols have always assumed that an adversary would not have access to information about any choices that are made during the process of encryption. "We are challenging this assumption," says...

We are on the cusp of a new information revolution – a quantum leap in technology – and the Institute for Quantum Computing (IQC) at the University of Waterloo is leading the way. With the world´s largest concentration of researchers working to harness the forces of quantum mechanics, the institute stands to transform computing, communications and other technologies. “We are learning to speak the language of the quantum realm – of atoms and electrons and...

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Open Systems & Information Dynamics
2012-05-17 15:20:56

Open Systems & Information Dynamics (OSID) is journal published by World Scientific. The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication,...

Foundations of Physics
2012-04-29 19:30:54

Foundations of Physics is a monthly-published journal devoted to the conceptual bases and fundamental theories of modern physics and cosmology, emphasizing the logical, methodological, and philosophical premises of modern physical theories and procedures. The journal publishes results and observations based on fundamental questions from all major fields of physics: quantum mechanics, quantum field theory, special relativity, general relativity, string theory, M-theory, cosmology,...

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...

Multiverse -- The term Multiverse was invented in December 1960, by Andy Nimmo, then vice chairman of the British Interplanetary Society, Scottish Branch, for a talk on the Everett many-worlds interpretation of quantum physics which had been published in 1957, to the branch. This was given in February 1961, and the word with its original definition, "an apparent universe, a multiplicity of which, go to make up the whole universe" was then first used. This was because the then dictionary...
