Multi-Qubit Gates chapter states the Swap gate is implemented as 2 CNOT gates.
It does not look like this is a sufficient, since the qubit 1 will be in q0 (+) q1 state after the second CNOT gate while the qubit 0 will be in q1 state.
Shouldn’t we add one more CNOT gate to flip qubit 1 state to q0 state?
