Performance Analysis of Quantum Repeaters Based Hybrid Communications Networks

Abstract

Abstract Towards offering efficient optical networks with regards to the cost and delay, the adaptation of quantum and classical communications can offer a solution to reduce high generated cost of implementing the bare quantum repeaters-based networks. In this paper, the performance of hybrid (classical-Quantum) networks that uses quantum repeaters is analysed and compared with bare quantum repeater network. In a distance, these repeaters are removed and replaced with classical base station. Several network metrics have been evaluated after modelling both quantum and hybrid networks, such as the latency, data rate, energy efficiency, scalability, power consumption and cost of implementation. The results show that the hybrid networks can offer faster connectivity, reduced cost, less required cost of operation and higher scalability. In contrary, the bare quantum repeater network showed higher data rate and higher energy efficiency.
