Black Holes: Getting Around The Firewall Paradox
2013-03-07 04:37:54

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Black holes are incredibly difficult objects to understand, partially because their very existence seemingly challenges the physical laws of the Universe. Because of their extreme nature, various peculiarities arise that give scientists pause. One such case was proposed by Stephen Hawking, the famed cosmologist, back in the 1970s. He noted that because of the extreme gravity that exists within the event horizon of a...

Physicists make first direct measurements of polarization states of light Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both overcomes some important challenges of Heisenberg's famous Uncertainty Principle and also is applicable to qubits, the building blocks of quantum information theory. They report their results in a paper published...

Discovery Made In The Quantum Realm

University of California - Santa Barbara Physicists at UC Santa Barbara are manipulating light on superconducting chips, and forging new pathways to building the quantum devices of the future —— including super-fast and powerful quantum computers. The science behind tomorrow's quantum computing and communications devices is being conducted today at UCSB in what some physicists consider to be one of the world's top laboratories in the study of quantum physics. A team in the...

Researchers Believe Quantum Satellites Will Be The Next Space Race
2013-03-01 20:16:16

Lee Rannals for redOrbit.com — Your Universe Online Two researchers from the University of Waterloo, Canada say the next big space race is building the first global quantum-communication satellite network. Up until now, the furthest quantum-communication signals have traveled is just a few hundred miles. However, this technology is up-and-coming, and is what Thomas Jennewein and Brendon Higgins believe will be driving the next space race. Quantum communication is the science...

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...

Surprising breakthrough could bolster quantum photonics, solar cell efficiency Scientists from the U.S. Department of Energy´s National Renewable Energy Laboratory and other labs have demonstrated a process whereby quantum dots can self-assemble at optimal locations in nanowires, a breakthrough that could improve solar cells, quantum computing, and lighting devices. A paper on the new technology, “Self-assembled Quantum Dots in a Nanowire System for Quantum Photonics,”...

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...

Quantum Dots Used To Generate Electricity From Waste Heat
2013-02-14 14:46:17

University of Rochester A new type of nanoscale engine has been proposed that would use quantum dots to generate electricity from waste heat, potentially making microcircuits more efficient. "The system is really a simple one, which exploits certain properties of quantum dots to harvest heat," Professor Andrew Jordan of the University of Rochester said. "Despite this simplicity, the power it could generate is still larger than any other nanoengine that has been considered until now."...

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...
