Using tiny radiation pressure forces -- generated each time light is reflected off a surface -- University of Oregon physicists converted an optical field, or signal, from one color to another. Aided by a "dark mode," the conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.
British Columbia Discovery Fund (VCC) Inc. is very pleased to announce that it has invested $2.0 million in D-Wave Systems, Inc. as the lead order that initiated a $30 million round of equity funding for D-Wave. Bezos Expeditions and In-Q-Tel (IQT) have also joined the investment round. Bezos Expeditions is the personal investment company of Jeff Bezos, the founder and CEO of Amazon.com, Inc. IQT is the strategic investment firm that delivers innovative technology solutions in support of the missions of the U.S. intelligence community.
To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter.
Recently, businessman Mike Lazaridis encouraged those present at the opening ceremony of the Mike & Ophelia Lazaridis Quantum-Nano Centre (QNC) to boldly go where no one has gone before.
In the relatively new scientific frontier of topological insulators, theoretical and experimental physicists have been studying the surfaces of these unique materials for insights into the behavior of electrons that display some very un-electron-like properties.
A research team from the University of Bristol's Centre for Quantum Photonics (CQP) have brought the reality of a quantum computer one step closer by experimentally demonstrating a technique for significantly reducing the physical resources required for quantum factoring.
An international research group led by scientists from the University of Bristol and the Universities of Glasgow (UK) and Sun Yat-sen and Fudan in China, have demonstrated integrated arrays of emitters of so call 'optical vortex beams' onto a silicon chip. The work is featured on the cover of the latest issue of Science magazine, published tomorrow [19 October 2012].
In a key step toward creating a working quantum computer, Princeton researchers have developed a method that may allow the quick and reliable transfer of quantum information throughout a computing device.
Qubit-based computing exploiting spooky quantum effects like entanglement and superposition will speed up factoring and searching calculations far above what can be done with mere zero-or-one bits. To domesticate quantum weirdness, however, to make it a fit companion for mass-market electronic technology, many tricky bi-lateral and multi-lateral arrangements---among photons, electrons, circuits, cavities, etc.---need to be negotiated.
If quantum computers are ever going to perform all those expected feats of code-breaking and number crunching, then their component qubits---tiny ephemeral quantum cells held in a superposition of internal states---will have to be protected from intervention by the outside world. In other words, decoherence, the loss of the qubits' quantum integrity, has to be postponed.
