Pygsti is a software package built to assess the performance of quantum computing processors. It implements algorithms organized into a variety of quantum characterization, verification, and validation (QCVV) protocols. These protocols are applied to as-built quantum processors by executing a prescribed set of circuits on the processor and analyzing the resulting data. We outline pygsti’s structure and demonstrate how it can help users assess and understand the sources of imperfection in a quantum processor.
