Performance Analysis of Quantum Channels

Topics in Quantum Networking

“…Technically, the development of quantum Internet requires a hybrid of technologies, which combine the features of both discrete variable systems and continuous variable systems [47]. Theoretically, it is necessary to formulate a system theory [66] for the dimension of the network dynamics, i.e., backlog, delay, and throughput, to deal with the quality-of-service requirements of the network applications and to help design and deploy the quantum networks.…”

“…We regard the queueing analysis as the canonical approach because of its pervasiveness and irreplaceability in networking. The queueing theory deals with the accumulation of the interarrival time and service time in time unit [69] or the accumulation of arrival quantity and service quantity in bit unit [66], based on which the performance measures are defined, e.g., backlog as the accumulated workload in the queue or the whole system, delay as the waiting time or sojourn time with respect to different scheduling schemes, and throughput as the traffic amount passing through the queueing system. A communication network is seen as a network of queues, due to the irregular randomness of the queue output, it is difficult to analyze the queueing networks and the queueing analysis based on the accumulation of bits usually has an advantage over the analysis based on the accumulation of time.…”
