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...

With headlines proclaiming the discovery of the Higgs boson–the so-called God particle–particle physics has captured the imagination of the world, particularly among those who dwell on the nature of the cosmos. But this is only one puzzle seemingly solved in a universe of mysteries. In a recent paper in Physical Review Letters, Dartmouth physicists delve into another enigmatic particle. Majorana is a name whose very mention evokes a veil of mystery. On one level, it refers to a...

Study describes greater chances of accessing more reliable information on applications in quantum computing and cryptography Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography and quantum computing. The findings, published in EPJ D´, are so robust that they enable access to the information even when the...

Scientists from the UK's National Physical Laboratory have developed a nano-device which could change the way we define electrical current A team of scientists at the National Physical Laboratory (NPL) and University of Cambridge has made a significant advance in using nano-devices to create accurate electrical currents. Electrical current is composed of billions and billions of tiny particles called electrons. NPL scientists have developed an electron pump — a nano-device —...

Quantum mechanics researchers show that nature is unpredictable Many of the predictions we make in everyday life are vague, and we often get them wrong because we have incomplete information, such as when we predict the weather. But in quantum mechanics, even if all the information is available, the outcomes of certain experiments generally can't be predicted perfectly beforehand. This inability to accurately predict the results of experiments in quantum physics has been the subject...

Brett Smith for redOrbit.com - Your Universe Online Now that the ℠God Particle´ has been discovered, is it time to pack up CERN´s Large Hadron Collider (LHC) and move on to other projects? Not so fast, say physicists who are looking to upgrade the 4-year-old particle accelerator. CERN´s governing body has just approved plans that would shut down the LHC for two years while it gets a $1.9 billion upgrade. The improvements would theoretically increase the power of...

Hunt For The Higgs: A Bet, A Glitch, And A Gateway
2012-07-05 15:29:04

Lawrence LeBlond for redOrbit.com - Your Universe Online About ten years ago British physicist Stephen Hawking was at a conference in South Korea when he made a small wager with University of Michigan physicist Gordon Kane that the long-theorized Higgs boson particle did not exist, a bet that Kane honored four years later, by sending the world renown physicist a check for $100, acknowledging that there was no Higgs. And then, just a few years later, in 2008, when the...

New Particle Discovery Could Be The Elusive Higgs Boson

Lawrence LeBlond for redOrbit.com - Your Universe Online The Fourth of July is a day of celebration for millions of people all across America, celebrating the birth of a nation. But in Geneva, Switzerland, a much different celebration is occurring as scientists at Europe´s CERN research center have revealed the discovery of a new subatomic particle, one that could be the elusive Higgs boson or “God particle.” The revelation was made at a seminar held at CERN today (July...

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,...

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...
