This pass manager applies the user-given initial layout. If none is given, and a trivial layout (i-th virtual -> i-th physical) makes the circuit fit the coupling map, that is used. Otherwise, the circuit is mapped to the most densely connected coupling subgraph, and swaps are inserted to map. Any unused physical qubit is allocated as ancilla space. The pass manager then unrolls the circuit to the desired basis, and transforms the circuit to match the coupling map. Finally, optimizations in the form of adjacent gate collapse and redundant reset removal are performed. Args: pass_manager_config: configuration of the pass manager. Returns: a level 1 pass manager. Raises: TranspilerError: if the passmanager config is invalid. defaultsabre translatorrouting)optimization_levellayoutN translationT)strict_directionF)remove_reset_in_zero optimization scheduling) layout_methodrouting_methodtranslation_methodoptimization_methodscheduling_method basis_gatestargetinit)pre_initrrrrpre_optimizationrr)rr coupling_mapinitial_layout init_methodrrrrrrget_passmanager_stage is_symmetricget_non_global_operation_namesrgenerate_pre_op_passmanager#generate_control_flow_options_checkr)rplugin_managerrr!r"r#rrrrrr routing_pmrrrr rschedrrs b/granary/edev/quantum/lib/python3.11/site-packages/qiskit/transpiler/preset_passmanagers/level1.pylevel_1_pass_managerr-sW*344N%1K&3L(7N%1>YK(5BM(7B7N,?O<-ANY+=J 'F 55>#616J ~55 m%8Q6   66)+>ST7K Z\6ZvDDVZD[[!= Lu   "=SXYYY!77+-@UV8L  0 0')r6s#"""""BBBBBB;;;;;;888888 ^^^^^^r.
