Compensates circuit against errors in zeta, chi and gamma angles by running calibrations on

The method calls prepare_floquet_characterization_for_moments to extract moments to characterize, run_calibrations to characterize them and make_zeta_chi_gamma_compensation_for_moments to compensate the circuit with characterization data.
Args | |
---|---|
circuit
|
Circuit to characterize and calibrate. |
sampler
|
cirq_google.Engine or cirq.Sampler object used for running the calibrations. When sampler is cirq_google.Engine or cirq_google.QuantumEngineSampler object then the calibrations are issued against a Google's quantum device. The only other sampler supported for simulation purposes is cirq_google.PhasedFSimEngineSimulator. |
processor_id
|
Used when sampler is cirq_google.Engine object and passed to cirq_google.Engine.run_calibrations method. |
gate_set
|
Used when sampler is cirq_google.Engine object and passed to cirq_google.Engine.run_calibrations method. |
options
|
Options that are applied to each characterized gate within a moment. Defaults to all_except_for_chi_options which is the broadest currently supported choice. |
gates_translator
|
Function that translates a gate to a supported FSimGate which will undergo characterization. Defaults to sqrt_iswap_gates_translator. |
merge_subsets
|
Whether to merge moments that can be characterized at the same time together. |
max_layers_per_request
|
Maximum number of calibration requests issued to cirq.Engine at a single time. Defaults to 1. |
progress_func
|
Optional callback function that might be used to report the calibration progress. The callback is called with two integers, the first one being a number of layers already calibrated and the second one the total number of layers to calibrate. |
permit_mixed_moments
|
Whether to allow mixing single-qubit and two-qubit gates in a single moment. |
