D-Wave Systems

D- Wave Systems Inc., a hardware manufacturer, headquartered in Burnaby, British Columbia, Canada. The company was founded in 1999 and known on 11 May 2011 by the development of the first commercial quantum computer to its specifications.

History

D-Wave was founded by Haig Farris, Geordie Rose, Bob Wiens and Alexandre Zagoskin 1999.

They sold a computer with 2011 claims to 128 qubits at Lockheed Martin and then received a funding of $ 30 million from Jeff Bezos, founder of Amazon, and the company In-Q -Tel, which is associated with the American CIA.

In May 2013, the purchase of a quantum computer by NASA and Google was announced. This computer should be able to count on 512 qubits, each qubit is represented by the direction of flow of current through superconducting loops on a chip.

Criticism

The computer is not a quantum computer in the original sense, for the realization of a quantum entanglement is essential ( instead, is a so-called adiabatic quantum computer). The fact that this D-Wave has succeeded in doubt critics. For this reason, it is in principle not possible to execute this computer the Shor algorithm. Instead, it performs adiabatic optimization problems. D-Wave is the opinion of critics yet also managed to unequivocally prove that their computer is faster than conventional computers with any problem. For example, it was possible, although the computer scientist Catherine McGeoh on tests, perform selected optimization tasks much faster than with standard PC software, but says this after McGeoh nothing about how fast the computer really is, and nothing about whether quantum effects on its performance play a role. Other studies that compare the performance of the D -Wave computer with a simulation of quantum computers, deliver date, no conclusive statements, whether quantum effects play a role.
