SYSTEMS AND METHODS FOR CALIBRATING THE ELEMENTS OF A QUANTUM PROCESSOR

摘要

Systems and methods for improving calibration procedures in a quantum processor architecture are described. For example, a dedicated calibration signal source is built into the architecture of the quantum processor for use during calibration. A single calibration signal source is communicatively coupled to many devices in the quantum processor architecture to provide an absolute calibration signal against which various parameters, responses, and/or behaviors of the many devices may be calibrated, either in series or in parallel. The use of a calibration signal source may reduce the time required to calibrate the elements of a quantum processor and/or improve the accuracy/precision of such calibrations.

1. A quantum processor comprising:
a plurality of devices, wherein at least a first device in the plurality of devices has a determinable parameter, and wherein the plurality of devices includes a plurality of qubits; a calibration signal source that is communicatively coupleable to at least the first device in the plurality of devices, wherein the calibration signal source provides a calibration signal; and a readout system that is communicatively coupleable to at least the first device in the plurality of devices, wherein the readout system reads out a signal that is dependent on both the calibration signal and the determinable parameter of the first device to determine a value for the determinable parameter of the first device.
