Efficient Scheme for Entanglement and Quantum Information Processing with Two Superconducting Quantum-Interference Devices in Cavity QED

In this paper,a scheme is proposed to create the entanglement of two superconducting quantum-interference devices (SQUIDs) and implement a two-qubit quantum phase gate between two SQUIDs in cavity.The scheme only requires resonant interactions.Thus the scheme is very simple and the quantum dynamics operation can be realized at a high speed,which isimportant in view of decoherence.
