ffsim.qiskit.pre_init_passes()[source]¶

Yield transpiler passes recommended for the Qiskit transpiler pre_init stage.

The following transpiler passes are yielded:

Decompose pass that decomposes PrepareHartreeFockJW and UCJOperatorJW gates to expose the underlying PrepareSlaterDeterminantJW and OrbitalRotationJW gates.
MergeOrbitalRotations pass to merge the Slater determinant preparation and orbital rotation gates.
