Quantum device performs 2.6 billion years of computation in 4 minutes

Photons explore quantum maze faster than possible for any classical computer.

I am a great believer in solving problems with lasers. Are you suffering from a severely polarized society and a fast-growing population living below the poverty line? Well, I have the laser to solve all your problems.

OK, maybe not. But when it comes to quantum computing, I believe that lasers are the future. I suspect that the current architectures are akin to the Colossus or the ENIAC: they are breakthroughs in their own right, but they are not the future. My admittedly biased opinion is that the future is optical. A new paper provides my opinion some support, demonstrating solutions to a mind-boggling 1030 problem space using a quantum optical system. Unfortunately, the support is a little more limited than I’d like, as it is a rather limited breakthrough.
