摘要
The quantum dynamics of two superconducting flux qubits in the presence of a nonclassical microwave field of a resonant cavity is investigated. We propose a quantum computing scheme, based on the sequential interaction of the Josephson qubits with the field mode, by which it is possible to generate "on demand" maximally entangled states of the two qubits. The effects of cavity losses on the system dynamics are carefully taken into account.
