Entanglement control over a quantum CDMA network

The purpose of this paper is to present a method of distributing quantum entanglement over a quantum CDMA network. We use this method to generate two maximally entangled states between two pairs of nodes which share one quantum channel. In this method, we use bright coherent light as the intermediate physical medium for transmitting quantum information. We do not choose the single-photon or weak coherent light sources which is widely-used in the previous work, because the bright coherent light is more easily to be realized in optical experiments. Through this method, quantum information from different pars of users can be transmitted through one channel, which will increase the capacity of the quantum channel.
