The benchmark tests show that the noise-free realization of QA can significantly outperform state-of-the-art classical algorithms. Quantum annealing (QA) is a cutting-edge algorithm that leverages the ...

In computer science, normally we care about asymptotic speedup: We care about, “What is your running time as a function of the size of the problem? Does it grow linearly? Does it grow quadratically?” ...

Are powerful quantum computers finally here? Google is claiming that its D-Wave quantum computer can solve certain problems 100 million times faster than an ordinary computer, a result that it says ...
