    While this is certainly quite nice, don't get your hopes up. Up to this point they've only created 1qubit. Plus, decoherence is probably a real nightmare in this system.

    More than ten years have passed since this...

    Any interesting/meaningful news?

    Now we have computers such as D-Wave, being D-Wave 2X the last version, with 1000 qubits approx.

    PS: shouldn't this thread be in PC Hardware?

    I remain convinced that electrical quantum computing is a boondoggle, funded solely to keep everyone's eyes off the prize. Optical.

    you cant keep a photon stationary (so to speak) and they get absorbed upon measurement unlike electrons

    That's a problem if you want to latch their state, if you can just build the entire pipeline for the algorithm it's irrelevant. You won't get a programmable quantum computer, but you can get a quantum codebreaker.

    Some massively parallel computations are trivial with optical, for instance FFT ... and there are quantum FFT equivalents which seem to also be relatively straightforward to implement (relative to electrical). An operation which happens to be quite important for Shor's algorithm.

    Electrical quantum computing is propagandised to keep people's eyes off the prize. Extremely high tech research build up to be extremely prestigious ... and which is extremely irrelevant.

    That's just because you're not holding on tight enough.

    Wouldn't you need a light touch ;)

    The sort of money needed to develop these things intel probably spent more developing core 2
