(Â鶹ÒùÔºOrg.com) -- Although the uncertainty principle is probably the most well-known example of a fundamental limitation of measurement precision in quantum mechanics, it is not the only one. In fact, every physical system ...
A team of scientists at UC Santa Barbara that helped pioneer research into the quantum properties of a small defect found in diamonds has now used cutting-edge computational techniques to produce a road map for studying defects ...
(Â鶹ÒùÔºOrg.com) -- In recent years, quantum computers have lost some of their luster. In the 1990s, it seemed that they might be able to solve a class of difficult but common problems — the so-called NP-complete problems ...
(Â鶹ÒùÔºOrg.com) -- For the first time, physicists have demonstrated the quantum entanglement of three light beams, all of different wavelengths. Entanglement of two light beams of different wavelengths has already been demonstrated, ...
How evolution acts to bridge the chasm between two discrete physiological states is a question that's long puzzled scientists. Most evolutionary changes, after all, happen in tiny increments: an elephant grows a little larger, ...
(Â鶹ÒùÔºOrg.com) -- One of the Holy Grails - so to speak - of science involves building quantum computers that can perform, with accuracy, the computations too advanced and too large for classical computers. While we remain ...
(Â鶹ÒùÔºOrg.com) -- Theoretically, quantum computing has the potential to work more efficiently and accurately than classical computing for certain processes, such as factoring. But quantum methods are experimentally challenging, ...
Digital logic, or bits, is the only paradigm for the IT world, and up to now researchers used it almost exclusively to study quantum information processing. But European scientists, in a series of firsts, have proved that ...
Scientists from France have shown that hypothetical axion-like particles cannot explain some unexpected observations in an Italian experiment carried out last year. Ruling out axions will likely subdue some of the renewed ...
The world's first commercially viable quantum computer was demonstrated yesterday in Silicon Valley by D-Wave Systems, Inc., a privately-held Canadian firm.
