The D-Wave OneTM is the world's first commercially available quantum computer. "Our superconducting 128-qubit processor chip is housed inside a cryogenics system within a 10 square meter shielded room." (images) In other words, it's a programmable superconducting integrated circuit with up to 128 pair-wise coupled superconducting flux qubits (video). The first D-Wave was sold in 2011 for a rumored $10 million. At first there was a lot of skepticism about it, but an August Nature study proved it worked by successfully solving "13 times out of 10,000 for four-amino-acid and six-amino-acid sequences under the Miyazawa-Jernigan model of lattice protein folding." Investors Jeff Bezos and The CIA are happy. A 2048 qubit system is in the works about 1 million times faster.
