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 or circuits to characterize. Only circuits with qubits of type GridQubit that can be covered by HALF_GRID_STAGGERED_PATTERN are supported|
||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.|
||Function that translates a gate to a supported FSimGate which will undergo characterization. Defaults to sqrt_iswap_gates_translator.|
||Whether to allow a mix of two-qubit gates with other irrelevant single-qubit gates.|
|List of FloquetPhasedFSimCalibrationRequest 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.|
