(color online) (a) and as a function of τP for different input states |ψin〉. The CNOT gate operation indicated by the dash line. (b) Eigenvalues as a function of exchange coupling J. (c) CNOT gate with superposition input states. The response shows that the target qubit follows the state of the control qubit. The figure comes from Ref. [17].
