My understanding (which is not very good here - I've only read one poorly written book on the subject, some years ago...) is that an N-bit quantum computer effectively lets you compute on 2^N things (See my hands waving?) at once. Which ain't half bad.
Hence, a 128-bit machine is a fairly hefty piece of tin, and well worth all that refrigeration: 2^128 is a Big Number, roughly 1E38. Bob On 13-10-12 02:30 PM, Raul Miller wrote:
With that kind of representation, I can see how a 128qubit machine could handle M=8. I suppose that's a start. Still: half the qubits get "wasted", and you'd need something considerably more general if you wanted to deal with other problems. Thanks,
