Maximally entangled states of two flux qubits in a microwave cavity
Rosanna Migliore, ANTONINO MESSINA · Physical Review B · 2005
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.
