Quantum algorithms – what we can do and what could we do Mathematical Challenges in Quantum Algorithms (51 pages) There are many things we can do with our quantum computers. For example: Factorise large integers and hence break RSA; Efficiently simulate quantum-mechanical systems; Solve certain search and optimisation problems faster than possible classically; . . …
New Scientist reports that Matthias Troyer of ETH Zurich in Switzerland has tested a D-Wave Two computer against a conventional, “classical” machine running an optimised algorithm – and they have found no evidence of superior performance in the D-Wave machine. DWave, Google and Lockheed remain optimistic of the usefulness of the machine and of future …
The scientific community accepts two models for building qubits and keeping them in quantum states—gate and adiabatic. D-Wave’s is adiabatic, and so is the 20-qubit model Christopher Monroe, the Bice Zorn Professor of Physics at the University of Maryland and fellow of the Joint Quantum Institute, has in his lab. Adiabatic quantum computers apply quantum …
As of Nov. 13, 2013, NASA’s Ames Research Center at Moffett Field in California’s Silicon Valley will begin facilitating news media interviews about its new quantum computing efforts. In a partnership with Google and independent, nonprofit research corporation Universities Space Research Association (USRA), Ames has established the Quantum Artificial Intelligence Laboratory (QuAIL) at its NASA …
1. Alex Selby has written his own specialist solver for one class of the McGeoch and Wang benchmarks that significantly outperforms the software (and D-Wave quantum annealing machine) tested by McGeoch and Wang on those benchmarks—and who provides the Python code. Summary Preliminary conclusions * FPTYTO ~= 10^5 faster than D-Wave (439 qubit) for Quadratic …
Scott Aaronson has commented upon the recent Dwave quantum computer speed tests. Scott has talked to the USC authors [when they visited MIT] of a paper which found quantum annealing in 100 qubits but did not find a speedup over classical systems for the 128 qubit processor. There were eight authors and Scott went with …
Geordie Rose has recently discussed Computional Universality and the Dwave Quantum computers. There’s another concept that has been recently introduced which is called a universal quantum computer. Such a machine is capable of simulating all quantum physics, which presumably includes as a subset all of classical physics. D-Wave’s current processor architecture is classically universal (can …
Lockheed Martin Corporation (NYSE: LMT) has entered into an agreement to purchase a quantum computing system from D-Wave Systems Inc. Lockheed Martin and D-Wave will collaborate to realize the benefits of a computing platform based upon a quantum annealing processor, as applied to some of Lockheed Martin’s most challenging computation problems. The multi-year contract includes …
Dwave Systems closed a $17M financing round as of the end of January 2008. These funds will be used primarily to push the level of integration of our chips into the low thousands of qubits by the end of the year. In parallel with this central effort we will be working on running experiments on …
