摘要：
We propose a generation scheme of chi-type entangled states based on weak cross-Kerr nonlinearities. After Homodyne measurement, the individual photons can be entangled together with the help of coherent states. Assisted with classical feed-forward, the generation efficiency of the entangled state nearly approaches unity. Depending on the currently available optical elements and techniques such as beam splitters, reflection mirrors, polarization beam splitters and classical feed-forward, the present scheme is expectable to realize in experiment.
