New Device For Quantum Information Processing
2012-07-24 11:14:28

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...

Scientists Make Strides Toward Quantum Computing

Lee Rannals for redOrbit.com - Your Universe Online Harvard scientists claim that they have solved a problem faced in quantum computing by using diamonds. One challenge quantum computing has faced is creating quantum bits that exist in a solid-state system at room temperature. Most systems rely on complex and expensive equipment designed to trap an atom or electron in a vacuum, and then cool the entire system to nearly absolute zero, or –459.67° Fahrenheit. The Harvard team...

USC scientists demonstrate that quantum computing could speed up the way web page ranks are calculated on the ever-expanding Internet Most people don't think twice about how Internet search engines work. You type in a word or phrase, hit enter, and poof — a list of web pages pops up, organized by relevance. Behind the scenes, a lot of math goes into figuring out exactly what qualifies as most relevant web page for your search. Google, for example, uses a page ranking algorithm...

Quantum Computers Move One Step Closer
2012-06-08 03:00:53

The quantum computer is a futuristic machine that could operate at speeds even more mind-boggling than the world´s fastest super-computers. Research involving physicist Mike Thewalt of Simon Fraser University offers a new step towards making quantum computing a reality, through the unique properties of highly enriched and highly purified silicon. Quantum computers right now exist pretty much in physicists´ concepts, and theoretical research. There are some basic quantum...

Efficient, Tunable Interface For Quantum Networks
2012-05-23 12:59:16

Quantum technologies promise to redefine the landscape of information processing and communication. We already live in an information age, in which vast amounts of data are sent around the world over optical fibers, but future quantum networks may be many times more powerful. These networks will require interfaces that can transfer information from quantum processors onto light particles (photons). Such interfaces will allow optical fibers to transmit information-bearing photons between...
