Abstract

This work describes how to implement a non-local xor function with coherent-state qubit using only linear optics devices and having efficiency equal to 1/2. The key element that makes possible the realization of the non-local xor function is a tripartite GHZ-type entangled coherent state. Its generation is proposed using an ideal lossless setup.
