Einstein's "Spooky Action" Theory Could Be Tested Aboard Space Station
2013-04-10 12:02:29

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...

German Researchers Take Next Step In Quantum Communications
2013-04-03 14:44:48

Brett Smith for redOrbit.com - Your Universe Online Quantum-based communications is still in its infancy, but the technology is widely expected to become used as the next generation of secure data transfer. According to a new report in Nature Photonics, a group of German physicists has announced the successful transmission of a quantum security key from an aircraft to a ground station via laser, overcoming one of the technology´s biggest hurdles: the ability to transmit and receive...

Carbon nanotubes can be used as quantum bits for quantum computers. A study by physicists at the Technische Universitaet Muenchen (TUM) has shown how nanotubes can store information in the form of vibrations. Up to now, researchers have experimented primarily with electrically charged particles. Because nanomechanical devices are not charged, they are much less sensitive to electrical interference. Using quantum mechanical phenomena, computers could be much more powerful than their...

Major Step Towards Quantum 'Internet' Signaled By Laser-like Photons
2013-03-19 13:30:09

University of Cambridge The realization of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the quantum 'internet'. The number of transistors on a microprocessor continues to double every two years, amazingly holding firm to a prediction by Intel co-founder Gordon Moore almost 50 years ago. If this is to continue, conceptual and technical advances...

Weizmann Institute researchers suggest one can affect an atom´s spin by adjusting the way it is measured One of the most basic laws of quantum mechanics is that a system can be in more than one state — it can exist in multiple realities — at once. This phenomenon, known as the superposition principle, exists only so long as the system is not observed or measured in any way. As soon as such a system is measured, its superposition collapses into a single state. Thus, we, who...

RUB researchers give floppy molecule a structure through solvent effects How you get the chameleon of the molecules to settle on a particular "look" has been discovered by RUB chemists led by Professor Dominik Marx. The molecule CH5+ is normally not to be described by a single rigid structure, but is dynamically flexible. By means of computer simulations, the team from the Centre for Theoretical Chemistry showed that CH5+ takes on a particular structure once you attach hydrogen molecules....

Einstein's 134th Birthday
2013-03-14 14:34:12

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 precise methodology of Richard Feynman's famous double-slit thought-experiment — a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave — has been followed in full for the very first time. Although the particle-wave duality of electrons has been demonstrated in a number of different ways since Feynman popularized the idea in 1965, none of the experiments have managed to fully replicate the methodology set out in Volume 3 of...

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...

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

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...
