Google, NASA: Our quantum computer is 100 million times faster than normal PC

Two years ago Google and NASA went halfsies on a D-Wave quantum computer, mostly to find out whether there are actually any performance gains to be had when using quantum annealing instead of a conventional computer. Recently, Google and NASA received the latest D-Wave 2X quantum computer, which the company says has “over 1000 qubits.” At an event yesterday at the NASA Ames Research Center, where the D-Wave computer is kept, Google and NASA announced their latest findings – and for highly specialised workloads, quantum annealing does appear to offer a truly sensational performance boost. For an optimisation problem involving 945 binary variables, the D-Wave X2 is up to 100 million times faster (108) than the same problem running on a single-core classical (conventional) computer. Google and NASA also compared the D-Wave X2’s quantum annealing against Quantum Monte Carlo, an algorithm that emulates quantum tunnelling on a conventional computer. […] Read More
