Quantum repeater in quantum networks (Conference Presentation)
Author(s): William J. Munro; Kae Nemoto

Paper Abstract

We have seen remarkable progress made over the last decade in the realization and exploitation of small-scale quantum communication technologies. The community is now at the stage where we need to consider how quantum repeaters and their associated networks are efficiently designed and implemented. This first requires us to define what a quantum repeater actually is and what functionality it requires. Associated with this is also the issue of its performance and when it is better than non-repeater approaches. In this talk, we explore such issues by taking incites from the conventional telecommunication world and use them to establish a framework for what quantum repeaters are and how their performance can be established. As part of this we clearly show that non-repeater approaches can exceed the direct transmission bounds. We extend these concepts to quantum networks and show one must be extremely careful when establishing the optimal communication bounds within them.
