✦ Synopsis
This work describes how to implement probabilistically the entangled state (j0 0 0i + j0 1 1i + j1 0 1i + j1 1 0i)/2, for coherent-state qubit, using only linear optics and measurements. Its creation is proposed firstly using an ideal lossless setup and secondly considering the decoherence caused by losses in the optical devices. The advantage of our scheme is the absence of single-qubit gates, photons counters and quantum teleportation, resources that are common in coherent state quantum information processing.

A theoretical scheme is presented for generating Gazeau-Klauder coherent states (GKCSs) via the generalization of degenerate Raman interaction with coupling constant to intensity dependent coupling. Firstly, we prove that in the intensity dependent degenerate Raman interaction, under particular cond
