cirq.google.prepare_floquet_characterization_for_operations

Extracts a minimal set of Floquet characterization requests necessary to characterize all the

operations within a circuit(s).

This variant of prepare method works on two-qubit operations of the circuit. The method extracts all the operations and groups them in a way to minimize the number of characterizations requested, depending on the connectivity.

Contrary to prepare_floquet_characterization_for_moments, this method ignores moments structure and is less accurate because certain errors caused by cross-talks are ignored.

The major advantage of this method is that the number of generated characterization requests is bounded by four for grid-like devices, where for the prepare_floquet_characterization_for_moments the number of characterizations is bounded by number of moments in a circuit.

The circuit can only be composed of single qubit operations, wait operations, measurement operations and operations supported by gates_translator.

circuit Circuit or circuits to characterize. Only circuits with qubits of type GridQubit that can be covered by HALF_GRID_STAGGERED_PATTERN are supported
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.
permit_mixed_moments Whether to allow a mix of two-qubit gates with other irrelevant single-qubit gates.

List of PhasedFSimCalibrationRequest for each group of operations to characterize.

IncompatibleMomentError when circuit contains a moment with operations other than the operations matched by gates_translator, or it mixes a single qubit and two qubit gates.
