Quantum entanglement for two qubits in a nonstationary cavity
Published 14 Oct 2016 in quant-ph, cond-mat.supr-con, and physics.optics | (1610.04665v1)
Abstract: The quantum entanglement and the probability of the dynamical Lamb effect for two qubits caused by non-adiabatic fast change of the boundary conditions are studied. The conditional concurrence of the qubits for each fixed number of created photons in a nonstationary cavity is obtained as a measure of the dynamical quantum entanglement due to the dynamical Lamb effect. We discuss the physical realization of the dynamical Lamb effect, based on superconducting qubits.
