In yesterday's issue of the journal Physical Review Letters researchers in China report they have performed a calculation in a problem that has 10^43 dimensions in Hilbert space 10^24 times faster than the largest conventional supercomputer using the best conventional algorithm can. The calculation solved was about something called "Boson Sampling" which doesn't seem to have much application in itself but is a good proof of concept that a Quantum Computer can do things that a conventional computer can't. Google solved a vastly smaller problem in Boson Sampling about a year ago and claimed quantum supremacy using a 53 qubit Quantum Computer, the Chinese used a 56 qubit Quantum Computer, that may seem like just a small increase but with Quantum Computers things build exponentially so that the problem the Chinese were able to solve was astronomically more complex than the one Google had solved a year ago.
