Abstract: 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.

Abstract: Systems and methods for calibrating and initializing a system comprising a first qubit, a second qubit, and a coupler are provided. A method of initializing the system can include calibrating the system; providing a first idle resonance frequency of the first qubit and a second idle resonance frequency of the second qubit; providing the first bias for the first idle resonance frequency and the second bias for the second idle resonance frequency; determining a value of the third resonance frequency at which a difference between the first degree of coupling and the second degree of coupling is minimized, when the first resonance frequency is the first idle resonance frequency and the second resonance frequency is the second idle resonance frequency; and providing the third bias according to the determined value of the third resonance frequency.
