Pass Manager Configuration.
|
||
|
||
Initialize a PassManagerConfig object
|
||
|
||
**Parameters**
|
||
|
||
* **initial\_layout** ([*Layout*](qiskit.transpiler.Layout "qiskit.transpiler.Layout")) – Initial position of virtual qubits on physical qubits.
|
||
* **basis\_gates** (*list*) – List of basis gate names to unroll to.
|
||
* **coupling\_map** ([*CouplingMap*](qiskit.transpiler.CouplingMap "qiskit.transpiler.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*](qiskit.transpiler.InstructionDurations "qiskit.transpiler.InstructionDurations")) – Dictionary of duration (in dt) for each instruction.
|
||
* **backend\_properties** ([*BackendProperties*](qiskit.providers.models.BackendProperties "qiskit.providers.models.BackendProperties")) – Properties returned by a backend, including information on gate errors, readout errors, qubit coherence times, etc.
|
||
* **seed\_transpiler** (*int*) – Sets random seed for the stochastic parts of the transpiler.
|
||
|
