Kozlowski, W. (author), Dahlberg, E.A. (author), Wehner, S.D.C. (author)The second quantum revolution brings with it the promise of a quantum internet. As the first quantum network hardware prototypes near completion new challenges emerge. A functional network is more than just the physical hardware, yet work on scalable quantum network systems is in its infancy. In this paper we present a quantum network protocol...conference paper 2020

(author), Elkouss Coronas, D. (author)Quantum key distribution allows for the generation of a secret key between distant parties connected by a quantum channel such as optical fibre or free space. Unfortunately, the rate of generation of a secret key by direct transmission is fundamentally limited by the distance. This limit can be overcome by the implementation of so-called...journal article 2018

van Dam, S.B. (author), Humphreys, P.C. (author), Rozpedek, F.D. (author), Wehner, S.D.C. (author), Hanson, R. (author)Quantum networks distributed over distances greater than a few kilometres will be limited by the time required for information to propagate between nodes. We analyse protocols that are able to circumvent this bottleneck by employing multi-qubit nodes and multiplexing. For each protocol, we investigate the key network parameters that determine...journal article 2017

Islam, Tanvirul (author), Wehner, S.D.C. (author)An efficient implementation of many multiparty protocols for quantum networks requires that all the nodes in the network share a common reference frame. Establishing such a reference frame from scratch is especially challenging in an asynchronous network where network links might have arbitrary delays and the nodes do not share synchronised...journal article 2016
