classPalindromePlacementStrategy¶source

bloqade.lanes.analysis.placement.strategy.PalindromePlacementStrategy

Bases: PlacementStrategyABC

Wraps any PlacementStrategyABC to emit ExecuteCZReturn for every CZ.

class PalindromePlacementStrategy(*, inner: PlacementStrategyABC)

Public import paths

• from bloqade.lanes.pipeline.logical import PalindromePlacementStrategy
• from bloqade.lanes.analysis.placement import PalindromePlacementStrategy
• from bloqade.lanes.heuristics.physical.movement import PalindromePlacementStrategy

On cz_placements: unwraps ExecuteCZReturn input to the home ConcreteState (via initial_layout), delegates to inner, then wraps the resulting ExecuteCZ in ExecuteCZReturn.

On sq_placements and measure_placements: unwraps ExecuteCZReturn to the home ConcreteState before delegating, so the inner strategy always sees a plain ConcreteState.

This replaces the insert_return_moves flag: choosing this strategy enables palindrome moves; using the bare inner strategy disables them.

Parameters

Name	Type	Description
inner	PlacementStrategyABC

Attributes
