Upcoming Talks

Entanglement-based SatQKD serves both as a near-term demonstrator and a benchmark for long-term global quantum networking. Understanding its practical performance is therefore essential to guide the next generation of missions and developments. In this seminar, we introduce a toolkit to dynamically model satellite communication channels, optimise finite key protocols, and bound the performance of upcoming missions. These finite-key rates serve as quantitative proxies for entanglement distribution capacity in large-scale quantum networks. This analysis enables informed trade-offs between satellite payload complexity, ground infrastructure, and achievable secure key throughput. More directly, we will also explore quantum repeater protocols developed for different satellite networks.

Jasminder Sidhu has worked in theoretical quantum optics, information, and communications. He works closely with experimentalists and engineers to model and guide the design of upcoming satellite quantum key distribution missions, including the UK Quantum Communications Hub mission, QUARC/ROKS, and the Canadian QEYSSat mission. He obtained his PhD from the University of Sheffield and an MSci in Physics from Imperial College London.
