Concentration Scheme for Partially Entangled Atomic States Through Detection of Cavity Decay
Song Wei · Communications in Theoretical Physics · 2008
We propose a scheme for concentrating entanglement of partially entangled states for atoms trapped in the distant cavities. The scheme is based on adiabatic passage and photonic interference. It is robust against a number of practical noises such as the violation of the Lamb–Dicke condition, spontaneous emission and detection inefficiency.
