MIT Researchers Create Best Ever Quantum Dots
2013-02-04 15:37:24

Michael Harper for redOrbit.com — Your Universe Online In the 1980s, scientists discovered very tiny particles that are capable of emitting light when exposed to ultraviolet light. These particles — now known as quantum dots — are made of a semiconductor material and can display light in a wide array of colors depending on the size of the particle. Though these dots initially showed great promise for a number of purposes, several limitations have prevented them from being...

Transporting At The Speed Of Light Into The Quantum Internet
2013-02-04 10:01:14

AlphaGalileo Not only do optical fibers transmit information every day around the world at the speed of light, but they can also be harnessed for the transport of quantum information. In the current issue of Nature Photonics, a research team of Innsbruck physicists led by Rainer Blatt and Tracy Northup report how they have directly transferred the quantum information stored in an atom onto a particle of light. Such information could then be sent over optical fiber to a distant atom....

Jedidiah Becker for redOrbit.com — Your Universe Online Over the years, the British cosmologist and theoretical physicist extraordinaire Stephen Hawking has become as well known for his ability to translate mind-boggling research about the universe into language that´s accessible to the layman as he is for his groundbreaking theoretical work in gravitational singularities and black hole radiation. This month, Cambridge´s wheelchair-bound conqueror of the cosmos turns 71....

Recycling In The Quantum World Could Lead To Better Teleportation

Alan McStravick for redOrbit.com - Your Universe Online What Einstein once referred to as “spooky action at a distance” could be our way into a 'Star Trek' future Watching the original 'Star Trek' series as a child, the most enthralling part of any episode was the moment they dissolved during teleportation on their way down to an alien planet. The science behind that at-one-time fiction shows it is now en route to becoming fact. The possibility of teleportation was first...

Quantum Object Behavior Depends On Measurement Apparatus Used
2013-01-09 14:54:07

University of Vienna Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus used for observing the system, and therefore on the type of measurement performed. Anton Zeilinger's team of physicists at the University of Vienna and the Austrian Academy of Sciences has recently taken this phenomenon further than ever. Whether a certain photon behaves like a particle or like a wave depends on...

Testing Einstein In Outer Space

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Two of the greatest scientific achievements of the last century were the establishment of the theories of Quantum Mechanics and General Relativity, both of which have withstood continual experimental scrutiny. However, a problem remains. The two theories seem to be at odds with each other. Researchers, for decades, have sought a theory that would combine the two realms — the large-scale gravity fields, and the...

Forget solid, liquid, and gas: there are in fact more than 500 phases of matter. In a major paper in today's issue of Science, Perimeter Faculty member Xiao-Gang Wen reveals a modern reclassification of all of them. Condensed matter physics — the branch of physics responsible for discovering and describing most of these phases — has traditionally classified phases by the way their fundamental building blocks — usually atoms — are arranged. The key is something...

While some theoretical physicists make predictions about astrophysics and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Such is the case at UC Santa Barbara, where theoretical physicists at the Kavli Institute for Theoretical Physics (KITP) cover the range of questions in physics. Recently, theoretical physicists at KITP have made important strides in studying a concept in quantum physics called quantum entanglement, in...

Scientists Offer New Insights Into Early Universe
2012-11-29 15:54:22

Lee Rannals for redOrbit.com — Your Universe Online Penn State University scientists using techniques from modern physics have developed a new understanding of the earliest eras in the history of the universe. The scientists now have an extended analyses that include quantum physics farther back in time than ever before, heading back to the very beginning. The new paradigm of loop quantum origins show that the large-scale structures we see in the universe evolved from...

Physics
2014-01-12 00:00:00

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...
