Just as a camera flash illuminates unseen objects hidden in darkness, a sequence of laser pulses can be used to study the elusive quantum behavior of a large "macroscopic" object. This method provides a novel tool of unprecedented performance for current experiments that push the boundaries of the quantum world to larger and larger scales. A collaboration of scientists led by researchers from the Vienna Center for Quantum Science and Technology (VCQ) at the University of Vienna report this...

New Breakthrough Could Double Wireless Capacity With No New Towers

  Rice's 'full-duplex' technology requires little hardware, could be ready for 4.5G networks The days of waiting for smartphones to upload video may be numbered. Rice University engineering researchers have made a breakthrough that could allow wireless phone companies to double throughput on their networks without adding a single cell tower. Rice's new "full-duplex" technology allows wireless devices like cell phones and electronic tablets to both "talk" and "listen" to wireless...

Image 1 - Digital Quantum Simulator Realized

  Almost two years ago Rainer Blatt's and Christan Roos' research groups from the University of Innsbruck recreated the properties of a particle moving close to speed of light in a quantum system. They encoded the state of the particle into a highly cooled calcium atom and used lasers to manipulate it according to equations proposed by the famous quantum physicist Paul Dirac. Thereby, the scientists were able to simulate so called Zitterbewegung (quivering motion) of relativistic...

Thanks to advances in experimental design, physicists at the National Institute of Standards and Technology (NIST) have achieved a record-low probability of error in quantum information processing with a single quantum bit (qubit)–the first published error rate small enough to meet theoretical requirements for building viable quantum computers. A quantum computer could potentially solve certain problems that are intractable using today's technology, even supercomputers. The NIST...

  Researchers have developed radio antennas that can be sewn into clothes. Ohio State University researchers created a prototype using plastic film and metallic thread. The team said the system's range is four times greater than that of a conventional antenna worn on the body. "Our primary goal is to improve communications reliability and the mobility of the soldiers," Chi-Chih Chen, one of the researchers, said in a press release. "But the same technology could work for...

TOKYO, August 19, 2011 /PRNewswire/ -- Renesas Mobile Corporation, a premier supplier of advanced cellular platforms, and Anritsu today announced that their industry leading collaboration in certification has developed and validated MIMO (Multiple Input, Multiple Output) test cases which have been accepted by 3GPP (RAN5). While MIMO has been available in the networks and some initial products are available, there have been no official certification requirements in place to...

Physicists at the National Institute of Standards and Technology (NIST) have discovered that the quantum properties of ions can be manipulated using microwaves, instead of lasers. Using microwaves enables the experiments to be made with a system that is one-tenth the size of conventional laser based systems. Compared to the laser sources, microwave components could be expanded to build practical quantum computing systems using thousands of ions for quantum computing and simulations....

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,...
