Quantum Computing And Mechanics See Two Breakthroughs
2012-09-20 13:22:33

April Flowers for redOrbit.com - Your Universe Online Two new studies, both published in Nature this week, outline incredible breakthroughs in the field of quantum mechanics. Australian engineers led an international team of researchers to create the first working quantum bit based on a single atom in silicon, potentially making another important step toward ultra-powerful quantum computing that theoreticians have dreamt of for decades. The team describes how they were able to read...

Michael Harper for redOrbit.com — Your Universe Online Some of us were born naturally inclined to understand numbers and their relationships to one another. The rest of us, sadly, depend on the work of these mathematically savvy individuals just to function in everyday life. As such, while some may have no issues understanding prime numbers and calculating them in their heads, others may get a headache once they count past 10. There are computers that exist, of course, which can...

New Perception Of The Remote Control Of Quantum Systems
2012-08-06 09:50:41

A fundamental characteristic of quantum physics is the fact that two or more particles can exhibit correlations stronger than classically allowed. This unique characteristic applies particularly to quantum entanglement: as soon as the quantum state of a particle is measured the state of its entangled partner changes accordingly, regardless of how far apart the two entangled particles might be. This feature allows for the remote quantum state preparation, which is an essential ingredient for...

Information Advantage Gained From Surprising Quantum Source
2012-08-06 09:34:56

New research lends hope that a phenomenon called quantum discord could be harnessed to bring quantum technologies within easier reach than expected. The work, by an international team, is published 5 August in Nature Physics. Up until a few years ago, researchers thought that realising quantum technologies would mean harnessing the most difficult-to-tame properties of the quantum world. For example, 'entanglement', the phenomenon referred to by Einstein as spooky-action-at-a-distance, was...

Single particles of light, also known as photons, have been produced and implemented into a quantum key distribution (QKD) link, paving the way for unbreakable communication networks. The results of the experiment, undertaken by a close collaboration of researchers based in Wuerzburg, Munich and Stuttgart, have been published today, Thursday 2 August, in the Institute of Physics and German Physical Society's New Journal of Physics. The single photons were produced using two devices made...

New Device For Quantum Information Processing

A groundbreaking new device from the National Physical Laboratory could help to usher in the long-awaited era of quantum computers Researchers at NPL have demonstrated for the first time a monolithic 3D ion microtrap array which could be scaled up to handle several tens of ion-based quantum bits (qubits). The research, published in Nature Nanotechnology, shows how it is possible to realize this device embedded in a semiconductor chip, and demonstrates the device's ability to confine...

Study describes greater chances of accessing more reliable information on applications in quantum computing and cryptography Theoretical physicist Filippo Miatto and colleagues from the University of Strathclyde, Glasgow, UK, have found a new method of reliably assessing the information contained in photon pairs used for applications in cryptography and quantum computing. The findings, published in EPJ D´, are so robust that they enable access to the information even when the...
