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.'"

A demo for the PS3 version of Final Fantasy XIII was released in Japan this week, and people have had a chance to try it out and report back. In fact, video footage of the demo in its entirety was streamed and then posted on YouTube shortly after finding its way into customers' hands. Eurogamer got a chance to give the demo a test-drive, and they had this to say: "The characters are likeable — Lightning for her mysteriousness, the members of NORA for their banter and camaraderie — the setting is compelling, and the whole thing is as sumptuous visually as you'd expect of a next-generation Square-Enix title. The plot's the only thing that I couldn't get a definite feel for from the demo, beyond the basic set-up of an oppressive regime, a resistance fighting against it and a character with mysterious powers brought to aid them in a twist of fate. But forty minutes with Final Fantasy XIII have left me with nothing but anticipation for what else it has in store."
