IBM Builds A Limited Quantum Computer

Posted by chrisd on from the soon-your-pgp-key-will-be-useless dept.

phr1 writes "IBM has announced and Yahoo has noted that the first working implementation of Shor's factoring algorithm. Using NMR techniques they built a seven-qubit quantum computer and factored the number 15 into the factors 3 and 5. This is by far the most complicated quantum computation ever done. It's quite an amazing feat--many people thought quantum computing was just a theoretical curiosity and Shor's algorithm could never be implemented in practice."

    If you put a cat inside this computer, will it die?

    So what about the 2 ton behemoths everyone's been buying for years? ;-)
    Big fucking atoms...

    7 Qbits already? That's great! No one should ever need more than 640 Qbits.

    7 qubits!?!? Sheesh, Noah's Ark was 300 qubits long, by 50 wide, by 30 high. And seven is supposed to be impressive thousands of years later?
