Classes in com.quantum4j.transpile.passes that implement TranspilerPass

Modifier and Type	Class	Description
final class	BasisGateDecompositionPass	Decomposes U1/U2/U3 gates into the RX/RY/RZ basis (and preserves measurements).
final class	CancelDoubleHPass	Removes adjacent pairs of H gates on the same qubit (H followed by H is identity).
final class	CancelDoubleXPass	A transpiler pass that cancels consecutive pairs of X gates on the same qubit.
final class	CancelDoubleZPass	Removes adjacent pairs of Z gates on the same qubit.
final class	CXCancellationPass	Peephole optimization: CX(a,b); CX(a,b) ==> (removed) Used to reduce circuit depth and simplify transpilation before routing.
final class	CXToCZDecompositionPass	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.
final class	GateCommutationPass	Local commutation optimizer.
final class	GateInversionPass	Produces the inverse (adjoint) of the unitary prefix of a circuit.
final class	RemoveRedundantMeasurementPass
final class	RotationFusionPass	Fuses consecutive same-axis rotations (RZ, RX, RY) on the same qubit by summing angles.
final class	SwapDecompositionPass	Decomposes SWAP gates into the canonical 3-CX sequence:
final class	U3DecompositionPass	Decomposes U1/U2/U3 gates into native rotations:
