Quantum Entanglement of Flux Qubits via a Resonator

Published 2002-07-08, updated 2002-07-25Version 2

We show that flux qubits can be efficiently entangled by inductive coupling to a tunable resonant circuit, in the scheme reminiscent of atoms' entanglement through the optical cavity mode. It is shown, in particular, that the single-photon excitation of the resonator produces the pure Bell state of qubits with the completely disentangled LC circuit.
