New Theory May Help Explain Why Nature Is Quantum
2013-05-14 12:41:52

Centre for Quantum Technologies at the National University of Singapore Like small children, scientists are always asking the question 'why?'. One question they've yet to answer is why nature picked quantum physics, in all its weird glory, as a sensible way to behave. Researchers Corsin Pfister and Stephanie Wehner at the Centre for Quantum Technologies at the National University of Singapore tackle this perennial question in a paper published 14 May in Nature Communications. We know...

Brighter Future From Photonic Quantum Computers
2013-05-13 12:40:14

University of Vienna Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the Faculty of Physics, University of Vienna succeeded in prototyping a new and highly resource efficient model of a quantum computer — the boson sampling computer. The results will be published in the upcoming issue of the renowned scientific journal "Nature...

Researchers Extend Electron Spin In Diamond For Incredibly Tiny Magnetic Detectors
2013-05-10 10:18:01

Lawrence Berkeley National Laboratory From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs — and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes. Now scientists at the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley...

D-Wave Quantum Computer Passes Important Computing Test
2013-05-09 17:57:32

Enid Burns for redOrbit.com — Your Universe Online Quantum computing just took a step from theory to practice with a test that took place at Amherst College in Massachusetts. An experimental quantum computer developed by D-Wave Systems was able to solve a problem 3,600 times faster than a conventional computer, the New York Times reports. Catherine McGeoch, the Beitzel Professor in Technology and Society in the computer science department at Amherst College administered the test....

Device For Portable, Ultra-precise Clocks And Quantum Sensors Developed By Scientists
2013-05-09 10:59:35

University of Strathclyde In a joint project between the Universities of Strathclyde and Glasgow, Imperial College London and the National Physical Laboratory, researchers have developed a portable way to produce ultracold atoms for quantum technology and quantum information processing. Their research has been published in the journal Nature Nanotechnology, where it is featured on the front cover. Many of the most accurate measurement devices, including atomic clocks, work by...

Quantum Internet Prototype In Use At Los Alamos
2013-05-07 15:49:02

Brett Smith for redOrbit.com - Your Universe Online As concerns over cyber security grow with each newly publicized attack, computer scientists have been pursuing quantum technology as a silver bullet against would-be hackers. According to a groundbreaking announcement, scientists at Los Alamos National Labs in New Mexico have been utilizing a small-scale “quantum internet” for the past two years. Quantum cryptography is possible because of the phenomenon known as quantum...

Laser Light Yields Versatile Manipulation Of A Quantum Bit
2013-05-01 15:09:02

University of California - Santa Barbara By using light, researchers at UC Santa Barbara have manipulated the quantum state of a single atomic-sized defect in diamond —— the nitrogen-vacancy center —— in a method that not only allows for more unified control than conventional processes, but is more versatile, and opens up the possibility of exploring new solid-state quantum systems. Their results are published in the latest edition of the Proceedings of the National...

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...
