Abstract

A system consisting of two Josephson qubits coupled through a quantum monochromatic electromagnetic field mode of aresonant tank circuit is studied. It is shown that for certain values of the parameters, it can be used as an entangling gate,which entangles the two qubits whilst the electromagnetic field remains disentangled. The gate operates with decent fidelity to a √SWAP gate and could form the basis for initial experimental investigations of coupled superconducting qubits.
