Quantum entanglement of flux qubits via a resonator

2015-12-17T10:05:19Z (GMT) by A. Yu Smirnov Alexandre Zagoskin
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.
