NASA, Google reveal quantum computing leap

The black box sitting at the heart of NASA's Advanced Supercomputing facility in Silicon Valley isn't much to look at. The size of a garden shed, it's smaller than a conventional supercomputer, but inside something quite impressive is happening.The box is a D-Wave 2X quantum computer, one of the most advanced examples yet of a new type of computer based on quantum mechanics, which can theoretically be used to solve complex problems in seconds rather than years.Quantum computers rely on fund
