com.quantum4j.core.gates.GateMatrices

public final class GateMatrices
extends Object

Pre-computed matrix representations for standard quantum gates. This class contains unitary matrices for: - Single-qubit gates - Parametric rotation gates - 2-qubit gates (CNOT, CZ, SWAP, ISWAP, CH) - 3-qubit CCX (Toffoli) NOTE: CNOT HAS BEEN FIXED to match Quantum4J's TwoQubitGate.apply() qubit-bit ordering (control=first argument, target=second).
