Twenty years before most scientists expected it, a commercial company has announced a quantum computer that promises to massively speed up searches and optimisation calculations.
D-Wave of British Columbia has promised to demonstrate a quantum computer next Tuesday, that can carry out 64,000 calculations simultaneously (in parallel “universes”), thanks to a new technique which rethinks the already-uncanny world of quantum computing. But the academic world is taking a wait-and-see approach.
… It has been predicted that quantum computing will make current computer security obsolete, cracking any current cryptography scheme by providing an unlimited amount of simultaneous processing resources. Multiple quantum states exist at the same time, so every quantum bit or “qubit” in such a machine is simultaneously 0 and 1. D-Wave’s prototype has only 16 qubits, but systems with hundreds of qubits would be able to process more inputs than there are atoms in the universe.
