Performance analysis of quantum channels

Abstract

Summary We study the quality of service in quantum channels. We regard the quantum channel as a queueing system, and present queueing analysis of both the classical information transmission and quantum information transmission in the quantum channel. For the former, we link the analysis to the classical queueing model, and for the latter, we propose a new queueing model and investigate the limit queueing behavior. For both scenarios, we obtain tail distributions of the performance measures, that is, backlog, delay, and throughput.

Entanglement Distribution in a Quantum Network: A Multicommodity Flow-Based Approach

“…To implement a full quantum internet the network needs to be able to produce entanglement between any two end nodes connected to the network [10]- [13]. The performance of such networks will depend on the quantum channels as well as the classical control units [14]. We refer to the book [1] and the papers [15]- [18] for a detailed technical introduction of a quantum Internet.…”

Three musketeers of a quantum channel: Backlog, delay, and throughput

“…Complementary to the engineering of the quantum networks, it is interesting to develop a theory for the dimension of the quantum networks considering different service requirements. In a recent paper, 1 Sun at Norwegian University of Science and Technology provides a mathematical framework for the study of the quality of service of the quantum channel with infinite storage space at the transceiver. This article adopts a layered perspective on the quantum network, which is similar to the layered network architecture of the classical networks with the physical layer, link layer, network layer, and so on.…”
