Claim 8:
9. The method of claim 8, further comprising:
determining an error rate for one or more other quantum computers, wherein said determining the error rate for the one or more other quantum computers comprises:
repeating, for a plurality of execution runs:
determining a set of possible execution run results for a respective one of the one or more other quantum computers;
determining respective probabilities for each of the possible execution run results for the other respective quantum computer based on applying each of the respective possible execution run results to a tensor network algorithm that models the other respective quantum computer; and
selecting, as a simulated execution run result for the respective execution run, one of the set of possible execution run results from the set of possible execution run results, wherein the selected simulated execution run result is selected from the set based on its determined probability relative to the determined probabilities of the other possible execution run results of the set which are rejected;

comparing a plurality of simulated execution run results for the plurality of execution runs of the benchmark quantum circuit on the one or more other quantum computer to a plurality of actual execution run results of the benchmark quantum circuit on the one or more other quantum computers; and
determining respective error rates for the one or more other quantum computers based on the respective comparisons of the simulated execution run results to the actual execution run results on the one or more other quantum computers.
