Abstract

A system for information transmission in a quantum communication network is provided. An embodiment of the system comprises:- a first laser signal source configured to generate a first laser signal, and- a second laser signal source configured to generate a second laser signal,wherein each laser signal source is configured to provide the corresponding laser signal to- a coupler unit, wherein said coupler unit is configured to receive and to couple both laser signals, and to provide coupled laser signals to- an optical waveguide, wherein said optical waveguide is configured to- receive the coupled laser signals and- cause a concentric alignment of the coupled laser signals by allowing the received coupled laser signals a mode propagation to provide concentrically aligned laser signals to- a directional unit, wherein said directional unit is configured to receive the concentric aligned laser signals and to provide the concentrically aligned laser signals to a second terminal of the quantum communication network.
