Although recent findings have poured cold water on quantum computing hype, don’t count the technology out yet. On 4 March, Google and XPrize announced a US $5 million prize to anyone who comes up with use cases for quantum computers. If that sounds like an admission that use cases don’t already exist, it isn’t, says...
