StructureAnalysisPass

class StructureAnalysisPass

Bases: BasePass

A pass that catalogs circuit structures used in a partitioned circuit.

If a circuit contains hierarchically defined gates, these hierarchies are discarded to check gate level equivalence between structures.

Example

The left shows a hierarchically defined gate sequence. The right shows the same gate sequence but it is specified at the gate level. These two structures are considered equivalent.
