    "abstract": "We give a detailed description of the entanglement purification protocol\nwhich generates maximally entangled states with high efficiencies from\nrealistic Gaussian continuous variable entangled states. The physical\nimplementation of this protocol is extensively analyzed using high finesse\ncavities and cavity enhanced cross Kerr nonlinearities. In particular, we take\ninto account many imperfections in the experimental scheme and calculate their\ninfluences. Quantitative requirements are given for the relevant experimental\nparameters.",
