The "quantum computer" is a good marketing gimmick, but the problem it solves is fairly uninteresting. See http://www.scottaaronson.com/blog/?p=1400 http://www.scottaaronson.com/blog/?p=1400 for some critical discussion of the D-Wave machine.
- brotchie 13y agoThe Ising model Hamiltonian that the D-Wave computer "evolves" almost directly maps to the energy equation you have to minimize to train a restricted Boltzmann machine. I wouldn't call this "uninteresting" given the rapid advances in leveraging Boltzmann machines for deep learning.
- mzl 13y agoOk, I agree that it can be interesting for some cases, but it is not at all what people expect when they hear "quantum computer". In addition, the comparisons with traditional methods for solving that problem show that you may as well solve the problem on normal hardware. Then the problem it solves stated as "Ising model Hamiltonian using quantum computer" is fairly uninteresting given that it is cheaper and simpler to solve the "Ising model Hamiltonian using classical hardware".
