Q40.Swap Protocol via 3 CNOT Gates
Circuit IdentitiesQubits: 2Q
Exchange the quantum states of two qubits WITHOUT using the SWAP gate.
Target Objective:
Use exactly three alternating CNOT gates (CX(0,1), CX(1,0), CX(0,1)) to swap the states of Qubit 0 and Qubit 1.
Judge Acceptance Criteria:
Statevector fidelity must reach ≥ 99.9% with the target unitary solution.
