Pass Manager Configuration for Clifford+T transpilation.

Parameters

• initial_layout (Layout | None) – Initial position of virtual qubits on physical qubits.
• basis_gates (list[str] | None) – List of basis gate names to unroll to.
• coupling_map (CouplingMap | None) – Directed graph representing a coupling map.
• instruction_durations (InstructionDurations | None) – Dictionary of duration (in dt) for each instruction.
• approximation_degree (float | None) – Heuristic dial used for circuit approximation, where 1.0 means no approximation (up to numerical tolerance) and 0.0 means the maximum approximation. If target is available, a value of None indicates that approximation is allowed up to the reported error rate for an operation in the target.
• seed_transpiler (int | None) – Sets random seed for the stochastic parts of the transpiler.
• timing_constraints (TimingConstraints | None) – Hardware time alignment restrictions.
• unitary_synthesis_method (str) – The string method to use for the UnitarySynthesis pass. Will search installed plugins for a valid method. You can see a list of installed plugins with unitary_synthesis_plugin_names().
• unitary_synthesis_plugin_config (dict | None) – The configuration dictionary that will be passed to the specified unitary synthesis plugin. Refer to the plugin documentation for how to use this.
• target (Target | None) – The backend target.
• hls_config (HLSConfig | None) – An optional configuration class to use for HighLevelSynthesis pass. Specifies how to synthesize various high-level objects.
• qubits_initially_zero (bool) – Indicates whether the input circuit is zero-initialized.
• rz_synthesis_config (dict | None) – An optional configuration class to use for SynthesizeRZRotations pass. Specifies how to synthesize RZ rotations in the circuit.
• _routing_disabled (bool)
