Before quantum computers begin to be deployed, how will we know if they work? The answer: quantum computer simulators. These important tools, now under development, run on the world’s most powerful supercomputing resources and still take days or weeks to complete quantum computing scenarios.
Now, a group of researchers at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) have invented a quantum computer simulator, called DM-SIM, that is 10 times faster than existing methods. The feat was detailed in one of only a handful of articles nominated for “Best Paper” at the annual international conference for high-performance computing, SC20.
