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...

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...

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...

Laser technique developed by CCNY and Berkeley researchers brings ultrafast computing closer to reality The promise of ultrafast quantum computing has moved a step closer to reality with a technique to create rewritable computer chips using a beam of light. Researchers from The City College of New York (CCNY) and the University of California Berkeley (UCB) used light to control the spin of an atom's nucleus in order to encode information. The technique could pave the way for quantum...

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...

Word of the Day
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
