Title: 2013-03-23 Quantum computing nearing realization Post by: lakeluke on March 23, 2013, 06:34:25 AM Interesting article, which might have some longer term ramifications to bitcoin's security.
"Now, Lockheed Martin — which bought an early version of such a computer from the Canadian company D-Wave Systems two years ago — is confident enough in the technology to upgrade it to commercial scale, becoming the first company to use quantum computing as part of its business. Skeptics say that D-Wave has yet to prove to outside scientists that it has solved the myriad challenges involved in quantum computation.

In the D-Wave system, a quantum computing processor, made from a lattice of tiny superconducting wires, is chilled close to absolute zero. It is then programmed by loading a set of mathematical equations into the lattice. The processor then moves through a near-infinity of possibilities to determine the lowest energy required to form those relationships. That state, seen as the optimal outcome, is the answer. Wow.

This has nothing to do with Bitcoin.

This has nothing to do with Bitcoin. This. D-Wave so called "quantum computers" do not use the quantum entanglement property, thus they can't break public key cryptography. They call them "quantum" because they use atoms for computation - that's all. Don't get confused by their marketing team who are obviously taking advantage of the terminology, perhaps to attract naive investors?

I am having troubles mining on my cpu already as it is. Hopefully btc goes up so I can afford a new cell phone and do some mining there as well, when I am not talking.
