April Flowers for redOrbit.com — Your Universe Online Since 1927, when Werner Heisenberg formulated the uncertainty principle, it has stood as one of the cornerstones of quantum mechanics. In a simplified form, the uncertainty principle states that it is impossible to measure anything without disturbing it. For example, any attempt to measure a particle's position must randomly change its speed. For clarity's sake, one should be aware that the uncertainty principle is not the same...

The Quantum World Can Be A Surprising Place

April Flowers for redOrbit.com - Your Universe Online Thermalization is the process of particles reaching thermal equilibrium through mutual interaction. We see this process around us every day. Take for example, ice cubes dropped into a pot of hot water. The cubes melt and cannot remain stable. Well-ordered ice crystals turn into a disordered liquid as the molecules of the ice and the molecules of the water reach thermal equilibrium, ending up at the same temperature. Research at the...

Quantum Teleportation Team Breaks The Distance Record
2012-09-06 11:12:39

April Flowers for redOrbit.com - Your Universe Online An international team of researchers, including physicists from the University of Vienna and the Austrian Academy of Sciences, has achieved quantum teleportation over a record distance of 143 kilometers. The experiment marks a major step towards satellite-based quantum communication. The team transmitted quantum states between the two Canary Islands of La Palma and Tenerife over a distance of 143 kilometers, beating the previous...

A revolutionary tool created by scientists at the University of Sheffield has enabled researchers to analyze nanometer-sized devices without destroying them for the first time, opening the door to a new wave of technologies. The nuclear magnetic resonance apparatus — developed by the University's Department of Physics and Astronomy — will allow for further developments and new applications for nanotechnology which is increasingly used in harvesting solar energy, computing,...

Scientists have discovered that a space inside a special type of carbon molecule can be used to imprison other smaller molecules such as hydrogen or water. The nano-meter sized cavity of the hollow spherical C60 Buckminsterfullerene – or bucky ball – effectively creates a 'nanolaboratory', allowing detailed study of the quantum mechanical principles that determine the motion of the caged molecule, including the mysterious wave-like behaviour that is a fundamental property of...

Berkeley Lab and UC Berkeley researchers record first direct observations of quantum effects in an optomechanical system A long-time staple of science fiction is the tractor beam, a technology in which light is used to move massive objects — recall the tractor beam in the movie Star Wars that captured the Millennium Falcon and pulled it into the Death Star. While tractor beams of this sort remain science fiction, beams of light today are being used to mechanically manipulate atoms or...

New Perception Of The Remote Control Of Quantum Systems
2012-08-06 09:50:41

A fundamental characteristic of quantum physics is the fact that two or more particles can exhibit correlations stronger than classically allowed. This unique characteristic applies particularly to quantum entanglement: as soon as the quantum state of a particle is measured the state of its entangled partner changes accordingly, regardless of how far apart the two entangled particles might be. This feature allows for the remote quantum state preparation, which is an essential ingredient for...

Information Advantage Gained From Surprising Quantum Source
2012-08-06 09:34:56

New research lends hope that a phenomenon called quantum discord could be harnessed to bring quantum technologies within easier reach than expected. The work, by an international team, is published 5 August in Nature Physics. Up until a few years ago, researchers thought that realising quantum technologies would mean harnessing the most difficult-to-tame properties of the quantum world. For example, 'entanglement', the phenomenon referred to by Einstein as spooky-action-at-a-distance, was...

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...
