    "abstract": "We propose a scheme to physically interface superconducting nano-circuits and\nquantum optics. We address the transfer of quantum information between systems\nhaving different physical natures and defined in Hilbert spaces of different\ndimensions. In particular, we investigate the transfer of the entanglement\ninitially in a non-classical state of a continuous-variable system to a pair of\nsuperconducting charge qubits. This set-up is able to drive an initially\nseparable state of the qubits into an almost pure, highly entangled state\nsuitable for quantum information processing.",
