Class CXToCZDecompositionPass

java.lang.Object

com.quantum4j.transpile.passes.CXToCZDecompositionPass

All Implemented Interfaces:

TranspilerPass

public final class CXToCZDecompositionPass
extends Object
implements TranspilerPass

Transpiler pass that decomposes CX/CNOT into: H(target) + CZ(control, target) + H(target) This pass is intentionally robust: it detects CNOT even if the gate did not originate from StandardGates.CNOTGate.
