A highly sensitive method to detect atoms was developed at the Vienna University of Technology Glass fiber cables are indispensable for the internet — now they can also be used as a quantum physics lab. The Vienna University of Technology is the only research facility in the world, where single atoms can be controllably coupled to the light in ultra-thin fiber glass. Specially prepared light waves interact with very small numbers of atoms, which makes it possible to build detectors...

Tossing quantum coins moves closer to reality Alice and Bob have broken up and have moved as far away from each other as possible. But they still have something to sort out: who gets to keep the car. Flipping a coin while talking on the phone to decide who gets to keep it just won't work. There's no trust. Neither believes each other's result. A paper published in Nature Communications by a team of researchers from Canada and Switzerland explores the concept of coin flipping in the...

Creating Light From A Vacuum
2011-11-19 05:05:04

Scientists at Chalmers have succeeded in creating light from vacuum — observing an effect first predicted over 40 years ago. The results have been published in the journal Nature. In an innovative experiment, the scientists have managed to capture some of the photons that are constantly appearing and disappearing in the vacuum. The experiment is based on one of the most counterintuitive, yet, one of the most important principles in quantum mechanics: that vacuum is by no means empty...

LIPTOVSKY MIKULAS, Slovakia, Nov. 16, 2011 /PRNewswire/ -- Theologian Miroslav Halza is making a name for himself by clarifying the mysteries of the Holy Bible in simple, logical terms that make sense to layman and scientist alike. In his previous book, The Chronology of Revelation, he explained the concept of "time" for both the visible and invisible worlds, based on elementary particles defined by quantum physics. In his latest book, he presents these same particles as carriers for other...

NORTH HOLLYWOOD, Calif., Nov. 9, 2011 /PRNewswire/ -- YOUR LOCAL GROCERY STORE -- A number of groceries are speaking out today in response to a recent series of crushed items in regional supermarkets. "You'd think people would learn," said Sunshine, a local OJ. "It's easy -- don't put me on top of the chips! It's just a disaster waiting to happen." "Enough is enough," said Sir Eggward, who has been broken up by the recent events. "We're simply not made to support the weight of all this...

How massless electrons tunnel through energy barriers in a carbon sheet called graphene Electrons moving in graphene behave in an unusual way, as demonstrated by 2010 Nobel Prize laureates for physics Andre Geim and Konstantin Novoselov, who performed transport experiments on this one-carbon-atom-thick material. A review article, just published in EPJ B´, explores the theoretical and experimental results to date of electrons tunneling through energy barriers in graphene. As good an...

When quantum mechanics meets general relativity The unification of quantum mechanics and Einstein's general relativity is one of the most exciting and still open questions in modern physics. General relativity, the joint theory of gravity, space and time gives predictions that become clearly evident on a cosmic scale of stars and galaxies. Quantum effects, on the other hand, are fragile and are typically observed on small scales, e.g. when considering single particles and atoms. That is...

A simple atomic nucleus could reveal properties associated with the mysterious phenomenon known as time reversal and lead to an explanation for one of the greatest mysteries of physics: the imbalance of matter and antimatter in the universe. The physics world was rocked recently by the news that a class of subatomic particles known as neutrinos may have broken the speed of light. Adding to the rash of new ideas, University of Arizona theoretical physicist Bira van Kolck recently...

Diamond, nature's hardest known substance, is essential for our modern mechanical world — drills, cutters, and grinding wheels exploit the durability of diamonds to power a variety of industries. But diamonds have properties that may also make them excellent materials to enable the next generation of solid-state quantum computers and electrical and magnetic sensors. To further explore diamonds' quantum computing potential, researchers from the University of Science and Technology of...

Researchers control the rate of photon emission from luminescent imperfections in diamond Engineers and physicists at Harvard have managed to capture light in tiny diamond pillars embedded in silver, releasing a stream of single photons at a controllable rate. The advance represents a milestone on the road to quantum networks in which information can be encoded in spins of electrons and carried through a network via light, one photon at a time. The finding was published in Nature...

Physics

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

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...
