Continuous variable entanglement purification and its physical implementation
We describe in detail an entanglement purification protocol which generates maximally entangled states with high efficiencies from realistic Gaussian continuous variable entangled states. A physical implementation of this protocol which uses high finesse cavities and cavity enhanced cross-Kerr nonlinearities is analysed.
