ALAPPlacePass dataclass 

ALAPPlacePass()

Bases: Pass

ALAP scheduling optimization for the place dialect.

Same pipeline as ASAPPlacePass but uses ALAP (As-Late-As-Possible) dependency scheduling. Deferring single-qubit gates to their latest valid layer reduces the qubit footprint of early CZ-anchored StaticPlacement regions, lowering atom-move overhead compared to ASAP.

debug.Info statements are stripped at the start of this pass (same reason as ASAPPlacePass).

ASAPPlacePass dataclass 

ASAPPlacePass()

Bases: Pass

              click bloqade.lanes.passes.ASAPPlacePass href "" "bloqade.lanes.passes.ASAPPlacePass"

ASAP scheduling optimization for the place dialect.

Merges all pure-gate placements (R, Rz, CZ), reorders gates by ASAP dependency scheduling, then fuses adjacent compatible gates.

debug.Info statements are stripped at the start of this pass. ASAP scheduling cannot reorder across opaque debug nodes, so they must be removed before the merge/reorder/fuse sequence. Use SequentialPlacePass if debug statements must be preserved.

SequentialPlacePass dataclass 

SequentialPlacePass()

Bases: Pass

              click bloqade.lanes.passes.SequentialPlacePass href "" "bloqade.lanes.passes.SequentialPlacePass"

Preserve gate order; merge only adjacent single-qubit-gate placements (R, Rz).

CZ placements remain isolated, preserving the original program order. This is the default behavior.

TransversalRewritePass dataclass 

TransversalRewritePass(
    *,
    transversal_location_map: Callable[..., Any],
    rewrite_logical_initialize: bool = True
)

Rewrite from logical to physical addresses.
