Google patents method to simulate quantum hardware performance

Google describes a computer method that uses a statistical model to generate virtual samples of quantum hardware. These samples represent different possible physical configurations and are used to simulate how the hardware would perform without building it.

Why it mattersThis could help engineers test and improve quantum computer designs more efficiently by predicting performance before manufacturing.

In the filing’s own words

A computer-implemented method for simulating quantum hardware performance can include accessing, by a computing system including one or more computing devices, a quantum hardware sample generation model configured to generate quantum hardware samples. The quantum hardware sample generation model can include one or more quantum hardware parameters. The computer-implemented method can include sampling, by the computing system, a quantum hardware sample from the quantum hardware sample generation model. The computer-implemented method can include obtaining, by the computing system, one or more simulated performance measurements based at least in part on the quantum hardware sample.

What exactly they claim (claim 1)

1. A computing system, the computing system comprising: one or more processors; and one or more memory devices, the one or more memory devices storing computer-readable data defining a quantum hardware sample generation model and instructions that, when implemented, cause the quantum hardware sample generation model to provide a quantum hardware sample; wherein the quantum hardware sample generation model comprises: one or more quantum hardware parameter distributions; one or more quantum hardware parameter dependencies defining relationships between the one or more quantum hardware parameter distributions; wherein the one or more quantum hardware parameter distributions and one or more quantum hardware parameter dependencies define a statistical network including a hardware distribution that, when sampled, produces a quantum hardware sample, the quantum hardware sample configured to model performance of quantum hardware.
