"A computation that would take 10,000 years on a classical supercomputer took 200 seconds on our quantum computer," said Brooks Foxen, a graduate student researcher in the Martinis Group. "It is likely that the classical simulation time, currently estimated at 10,000 years, will be reduced by improved classical hardware and algorithms, but, since we are currently 1.5 trillion times faster, we feel comfortable laying claim to this achievement."

The feat is outlined in a paper in the journal Nature.
