Book ChapterDOI
Implementing the Tate Pairing
TL;DR: Methods to quickly compute the Tate pairing, and hence enables efficient implementation of these cryptosystems, are provided and division-free formulae for point tripling on a family of elliptic curves in characteristic three are given.
Journal ArticleDOI
Quantum communication without the necessity of quantum memories
William J. Munro,William J. Munro,Ashley M. Stephens,Simon J. Devitt,Keith Alexander Harrison,Kae Nemoto +5 more
TL;DR: In this paper, the authors proposed a design of quantum communication based on directly transmitting quantum information in encoded form across a network, which does not require entangled links between nodes and long-lived quantum memories.
Journal ArticleDOI
From quantum multiplexing to high-performance quantum networking
William J. Munro,William J. Munro,Keith Alexander Harrison,Ashley M. Stephens,Simon J. Devitt,Kae Nemoto +5 more
TL;DR: In this paper, the authors describe a theoretical mechanism that may ensure high-fidelity entanglement of photons, and thus could be used to construct a practical quantum repeater The communication rate is shown to be a function of the maximum distance between any two adjacent quantum repeaters, rather than of the entire length of the network.
Book ChapterDOI
Applications of Multiple Trust Authorities in Pairing Based Cryptosystems
TL;DR: This work investigates a number of issues related to the use of multiple trust authorities and multiple identities in the type of identifier based cryptography enabled by the Weil and Tate pairings and investigates how one can equate a trust authority with a way to add contextual information to an identity.

Quantum communication without the necessity of quantum memories
William J. Munro,William J. Munro,Ashley M. Stephens,Simon J. Devitt,Keith Alexander Harrison,Kae Nemoto +5 more
TL;DR: Researchers propose a design of quantum communication based on directly transmitting quantum information in encoded form across a network that potentially provides higher communication rates than existing entanglement-based schemes.
