    "abstract": "A novel scheme is proposed for realizing quantum entanglement, quantum\ninformation transfer and a set of universal quantum gates with\nsuperconducting-quantum-interference-device (SQUID) qubits in cavity QED. In\nthe scheme, the two logical states of a qubit are the two lowest levels of the\nSQUID. An intermediate level of the SQUID is utilized to facilitate coherent\ncontrol and manipulation of quantum states of the qubits. The method presented\nhere does not create finite intermediate-level population or cavity-photon\npopulation during the operations. Thus, decoherence due to spontaneous decay\nfrom the intermediate levels is minimized and the requirement on the quality\nfactor of the cavity is greatly loosened.",
