1. A system, comprising:
a memory that stores computer executable components; and
a processor that executes the computer executable components stored in the memory, wherein the computer executable components comprise:
an execution component that directs execution, employing a quantum processor, of an error mitigation set of quantum circuits that were noise-adjusted by employing noise scaling; and
an evaluation component that evaluates, at an evaluation, results of the execution of the error mitigation set of quantum circuits,
wherein the evaluation comprises a first generation of a first average expectation value corresponding to a noise-attenuated result of the execution, and
wherein the evaluation further comprises a second generation of a second average expectation value corresponding to a noise-amplified result of the same execution.
