In a paper briefly published on a NASA server in mid-September, Google detailed the outcome of a computer experiment wherein a quantum computer solved a computational problem that would otherwise have been practically impossible for a traditional supercomputer to have performed, and in doing so having achieved a milestone knownread more

An international team of researchers has definitively proven that quantum computers can hold a significant computational advantage over classical semiconductor-based computers.

Although quantum computing elements have been available in D-Wave Systems‘ series of computers for over a decade, there has been a great deal of controversy over whether or not the performance increases demonstrated by these computers are actually due to quantum processes, and not simply efficiencies hidden in the computer’s code or hardware.
