| [`level_0_pass_manager`](qiskit.transpiler.preset_passmanagers.level_0_pass_manager "qiskit.transpiler.preset_passmanagers.level_0_pass_manager")(pass\_manager\_config) | Level 0 pass manager: no explicit optimization other than mapping to backend. |

|
| [`level_1_pass_manager`](qiskit.transpiler.preset_passmanagers.level_1_pass_manager "qiskit.transpiler.preset_passmanagers.level_1_pass_manager")(pass\_manager\_config) | Level 1 pass manager: light optimization by simple adjacent gate collapsing. |

| [`level_2_pass_manager`](qiskit.transpiler.preset_passmanagers.level_2_pass_manager "qiskit.transpiler.preset_passmanagers.level_2_pass_manager")(pass\_manager\_config) | Level 2 pass manager: medium optimization by initial layout selection and gate cancellation using commutativity rules. |
