Finally a proof that quantum computers outperform classical computers for a certain class of problems? Thoughts?
"Quantum computers are expected to be better at solving certain computational problems than classical computers. This expectation is based on (well-founded) conjectures in computational complexity theory, but rigorous comparisons between the capabilities of quantum and classical algorithms are difficult to perform. Bravyi et al. proved theoretically that whereas the number of “steps” needed by parallel quantum circuits to solve certain linear algebra problems was independent of the problem size, this number grew logarithmically with size for analogous classical circuits (see the Perspective by Montanaro). This so-called quantum advantage stems from the quantum correlations present in quantum circuits that cannot be reproduced in analogous classical circuits." http://science.sciencemag.org/content/362/6412/308 Cheers, Telmo. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
