New from me at Wired:
Google launched its Quantum A.I. Lab last year to test a machine called the D-Wave Two, an intriguing but controversial system that its makers bill as a quantum computer, and it believes quantum computing could play a key role in so many of its future ambitions, from self-driving cars and other robots to better predictive analytics systems for products like Google Now to things we haven’t even dreamed up yet. Thanks to what’s called the superposition principle of quantum mechanics, it could process data for such projects at speeds that are exponentially faster than what you get from today’s machines.
But the scientific community has greeted the D-Wave machine with skepticism, questioning whether the machine is actually a quantum computer at all, and whether it can actually provide something you can’t get from conventional machines. In joining Google, Martinis lends new weight to the company’s quantum ambitions.
