An international team of scientists has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level. The electrical currents currently used to power electronic devices are generated by a flow of charges. However, emerging quantum technologies such as spin-electronics, make use of both charge and another intrinsic property of electrons — their spin — to transfer and...

Major Step Towards Quantum 'Internet' Signaled By Laser-like Photons

University of Cambridge The realization of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the quantum 'internet'. The number of transistors on a microprocessor continues to double every two years, amazingly holding firm to a prediction by Intel co-founder Gordon Moore almost 50 years ago. If this is to continue, conceptual and technical advances...

Wave Properties of Individual Heavy Molecules Can Also Be Observed Experimentally/Video Shows Development of Interference Pattern in (Nearly) Real Time Quantum theory describes the world of atoms very precisely. Still, it defies our macroscopic conception of everyday´s world due to its many anti-intuitive predictions. The wave-particle dualism probably is the best known example and means that matter may spread and interfere like waves. Now, an international team of researchers has...

News from the American Physical Society Hydrodynamics of writing with ink Jungchul Kim, Myoung-Woon Moon, Kwang-Ryeol Lee, L. Mahadevan, and Ho-Young Kim Physical Review Letters (forthcoming) For millennia, writing has been the preferred way to convey information and knowledge from one generation to another. We first developed the ability to write on clay tablets with a point, and then settled on a reed pen, as preserved from 3000 BC in Egypt when it was used with papyrus. This...

UBC, California researchers find a way to quash decoherence Researchers have made a major advance in predicting and quashing environmental decoherence, a phenomenon that has proven to be one of the most formidable obstacles standing in the way of quantum computing. The findings "“ based on theoretical work conducted at the University of British Columbia and confirmed by experiments at the University of California Santa Barbara "“ are published online in the July 20 issue of the...

Researchers develop quantum a computing system that resists 'quantum bug' Scientists have taken the next major step toward quantum computing, which will use quantum mechanics to revolutionize the way information is processed. Quantum computers will capitalize on the mind-bending properties of quantum particles to perform complex calculations that are impossible for today's traditional computers. Using high magnetic fields, Susumu Takahashi, assistant professor in the USC Dornsife College of...

A new fractional vortex state observed in an unconventional superconductor may offer the first glimpse of an exotic state of matter predicted theoretically for more than 30 years. In a paper published in the January 14 issue of Science, University of Illinois physicists, led by Raffi Budakian, describe their observations of a new fractional vortex state in strontium ruthenium oxide (SRO). Such states may provide the basis for a novel form of quantum computing in which quantum information is...

Entanglement is a fascinating property connecting quantum systems. Albert Einstein called it the "spooky action at a distance". This bizarre coupling can link particles, even if they are located on opposite sides of the galaxy. The strength of their connections is behind the promising quantum computers, the dream machines capable of quick and efficient computations. The team lead by Rainer Blatt at the Institute of Experimental Physics of the University of Innsbruck has been working very...

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,...

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
