Abstract

We propose and analyze a scheme for the selective reset of a chain of inductively coupled Josephson flux qubits initially prepared in a multipartite entangled state. The possibility of controlling at will the coupling between two prefixed qubits is exploited to drive a "generalized W state" to a factorized state with only one qubit in the excited state and all the other qubits in their own ground states.
