Programmable Quantum Computer Created 132

Posted by Soulskill on Thursday November 26, 2009 @12:41PM from the four-out-of-five-ain't-bad dept.

An anonymous reader writes "A team at NIST (the National Institute of Standards and Technology) used berylium ions, lasers and electrodes to develop a quantum system that performed 160 randomly chosen routines. Other quantum systems to date have only been able to perform single, prescribed tasks. Other researchers say the system could be scaled up. 'The researchers ran each program 900 times. On average, the quantum computer operated accurately 79 percent of the time, the team reported in their paper.'"

New Theory of Gravity Decouples Space & Time 575

eldavojohn writes "Petr Horava, a physicist at the University of California in Berkeley, has a new theory about gravity and spacetime. At high energies, it actually snips any ties between space and time, yet at low energies devolves to equivalence with the theory of General Relativity, which binds them together. The theory is gaining popularity with physicists because it fits some observations better than Einstein's or Newton's solutions. It better predicts the movement of the planets (in an idealized case) and has a potential to create the illusion of dark matter. Another physicist calculated that under Horava Gravity, our universe would experience not a Big Bang but a Big Bounce — and the new theory reproduces the ripples from such an event in a way that matches measurements of the cosmic microwave background."

Submission + - You probably should have used a MAC

coreboarder writes: So tonight Rodney, the geek, in Stagate Atlantis glibly advised an alien that he should have used a MAC due to system failure. Fiction aside, how much of an issue is the much touted stability of OS X in your os selection? Is OS X really as 'rock solid' as claimed? If not, where, how, and most importantly why does it fail?
