Quantum computing system calibration method
A recently granted patent (Publication Number: US11875222B1) outlines a method executed in a quantum computing system that involves performing a calibration process to identify the value of an operating parameter. This process includes measurements on a quantum computing device, interpreting these measurements to extract control parameters, and determining stability by analyzing variations in response to changes in system conditions. The method also involves updating a stability model based on this analysis, scheduling recalibration based on predicted future values, and executing quantum algorithms based on the identified operating parameter.
Furthermore, the patent describes a quantum computing system comprising a quantum processor cell with qubit devices and a control system. This system is configured to perform operations such as calibration processes, stability analysis, updating stability models, scheduling recalibrations, and executing quantum algorithms. The system may include sensors to monitor the condition of the quantum computing system, with data obtained from these sensors used to analyze variations in the operating parameter. The operating parameter can include voltage, phase, frequency, time duration, Rabi rate, or Rabi rotation angle, with stability determined by analyzing drift over time. This patent highlights advancements in quantum computing systems and their calibration processes to optimize performance and accuracy in executing quantum algorithms.
