This pass manager applies the user-given initial layout. If none is given, a search for a perfect layout (i.e. one that satisfies all 2-qubit interactions) is conducted. If no such layout is found, and device calibration information is available, the circuit is mapped to the qubits with best readouts and to CX gates with highest fidelity. The pass manager then transforms the circuit to match the coupling constraints. It is then unrolled to the basis, and any flipped cx directions are fixed. Finally, optimizations in the form of commutative gate cancellation, resynthesis of two-qubit unitary blocks, redundant reset removal and final layout improvements are performed. Args: pass_manager_config: configuration of the pass manager. Returns: a level 3 pass manager. Raises: TranspilerError: if the passmanager config is invalid. defaultrouting)optimization_level) layout_methodrouting_methodtranslation_methodoptimization_methodscheduling_method basis_gatestargetinitlayoutN translation optimization scheduling)pre_initrrr rrr)rr coupling_mapinitial_layout init_methodr rrrrrget_passmanager_stager#generate_control_flow_options_checkr)pass_manager_configplugin_managerrrrrr rrrrr routing_pmrrrr rrscheds f/home/james-whalen/.local/lib/python3.13/site-packages/qiskit/transpiler/preset_passmanagers/level3.pylevel_3_pass_managerr$s034N%11K&33L(77N%11>YK'55BM(77D9N,??L9-AANY+==J ' 'F 55>16J 99#%-/+H  / / Q 0 D~55 mQ6  66)ST7K"77+UV8L  0 0'QR 1 E  !
