Abstract

A high fidelity quantum transfer scheme for continuous variable states based on coupled resonator waveguide network is presented. We first give the transfer scheme of an arbitrary superposition of coherent states by using single coupled resonator waveguide, next we give the transfer scheme of entangled coherent states by using two parallel coupled resonator waveguides, and finally give the transfer scheme of continuous variable cluster states by using four parallel coupled resonator waveguides. The fidelity of all schemes is up to 100%.
