D-Wave Systems Inc. is a hardware manufacturer headquartered in Burnaby , British Columbia , Canada . The company was founded in 1999 and became known on May 11, 2011 for the development of what they say was the first commercial quantum computer .
history
D-Wave was founded in 1999 by Haig Farris , Geordie Rose , Bob Wiens and Alexandre Zagoskin .
In 2011 they sold a computer that they said had 128 qubits to Lockheed Martin and then received $ 30 million in funding from Jeff Bezos , founder of Amazon , and the company In-Q-Tel , which is assigned to the American secret service CIA.
In May 2013, NASA and Google announced the purchase of a quantum computer. This computer should be able to calculate on 512 Qbits, whereby each Qbit 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 which the realization of a quantum entanglement is essential (instead it is a so-called adiabatic quantum computer ). Critics doubt that D-Wave succeeded in doing this. For this reason it is in principle not possible to run the Shor algorithm on this computer . Instead, it performs adiabatic optimization problems. In the opinion of critics, D-Wave has not yet succeeded in proving beyond any doubt that their computer is faster than conventional computers in any problem. For example, the computer scientist Catherine McGeoch succeeded in tests in executing selected optimization tasks much faster than with conventional PC software, but according to McGeoch this says nothing about how fast the computer really is, and also nothing about whether quantum effects in its performance play a role. Other studies that compare the performance of the D-Wave computer with a simulation of quantum computers have so far not provided any clear statements as to whether quantum effects play a role.
In 2014, customer studies could not find any advantage over optimized algorithms on conventional hardware, whereupon Google announced its own hardware developments.
On December 8, 2015, it was announced in a blog post by Google that certain calculations on the quantum computer acquired in 2013 were 100 million times faster than on conventional computers.
