Comment Re:Does anyone understand this? (Score 1) 60

Perhaps wouldn't, not couldn't. The "so what" of this article is that they're reproducing a past result, by doing physics experiments with an entangled system -- it's a kind of verification; about all the "proof" you can ever get about an analog computer, by my understanding. It also shows a use beyond just SAT and factoring which looks rather novel to me, but apparently Feynman suggested it.

Comment Re:Quantum computing? (Score 1) 278

Most quantum computing efforts are purely electrical in their implementations, so the entangled objects are "massless" (cough cough electrons have mass). Entanglement of photons has been long-since demonstrated. This "massive" entanglement involves moving mass around. I'm not impressed by the technicality but curious about its applications

Comment 2007 called, it wants its news back (Score 1) 204

D-Wave recently released its DW2000Q qubits. Where 2000 qubits are guaranteed to be calibrated, the actual device contains 2048 qubits. D-Wave operates its refrigerators around half the temperature, and 48 qubits is their acceptable error margin. So, good job, Intel, your hot quantum computer is dinky and negligibly small
