Class CXCancellationPass

java.lang.Object

com.quantum4j.transpile.passes.CXCancellationPass

All Implemented Interfaces:

TranspilerPass

public final class CXCancellationPass
extends Object
implements TranspilerPass

Peephole optimization: CX(a,b); CX(a,b) ==> (removed) Used to reduce circuit depth and simplify transpilation before routing. This pass is idempotent and preserves semantic equivalence.
