Accurately predicting a quantum processor's capability is currently difficult, reports Charles Q. Choi. However, new benchmarks developed by Sandia National Labs measure a quantum computer's performance based on a combination of tasks, compared with existing standards that generate just one number.
"Quantum computers are complicated, and quantifying their performance is complicated, too,” says Tim Proctor of Sandia National Laboratories' Quantum Performance Laboratory. "Ultimately, we think that benchmarks built using our method could be used to design a set of comprehensive tests for quantum computers. This would make it possible to accurately compare quantum computers and to find out which hardware is best for which task."
