Qbits unstable: May Limit Quantum Computing

Posted by timothy on from the that-would-be-a-downer dept.

museumpeace writes "Netherlands Organiztion for Scientific Research provies a human-readable description of research into the stability of Qbits conducted at Leiden University. The bad news: " Much to their surprise they discovered that the coherence tends to spontaneously disappear, even without external influences." The whole story in physicist-readable form is in the June 17 Physical Review Letters by van Wezel, van den Brink, Zaanen [click abstract or huge PDF]. I am not buying any quantum computing startups 'til they nail this matter down...you can't build a computer if state information is going to evaportate in a second or less."

    Explain to me how gravity works, or stop using it.

    The quality of spelling/grammar on /. is so far down in the toilet that it needs to be flushed.
