Parameters

• initial_layout (Layout) – Initial position of virtual qubits on physical qubits.

• basis_gates (list) – List of basis gate names to unroll to.

• coupling_map (CouplingMap) – Directed graph represented a coupling map.

• layout_method (str) – the pass to use for choosing initial qubit placement.

• routing_method (str) – the pass to use for routing qubits on the architecture.

• translation_method (str) – the pass to use for translating gates to basis_gates.

• scheduling_method (str) – the pass to use for scheduling instructions.

• instruction_durations (InstructionDurations) – Dictionary of duration (in dt) for each instruction.

• backend_properties (BackendProperties) – Properties returned by a backend, including information on gate errors, readout errors, qubit coherence times, etc.

• approximation_degree (float) – heuristic dial used for circuit approximation (1.0=no approximation, 0.0=maximal approximation)

• seed_transpiler (int) – Sets random seed for the stochastic parts of the transpiler.

• timing_constraints (TimingConstraints) – Hardware time alignment restrictions.
