Report on Quantum Position Verification Workshop at Lorentz Center

Description and aims

Quantum position verification (QPV) is emerging as a promising way to use quantum communication to establish trust based on location without requiring any pre-shared keys. This is impossible without the use of quantum information, making it a truly new capability of quantum networks. Recent research has both seen experimental advances towards implementing QPV, and deep theoretical connections between QPV protocol analysis and foundational questions in cryptography and physics. This workshop brought together theoretical and experimental researchers, to advance the understanding of QPV implementations, security proofs and potential loopholes, and to explore connections to a variety of fields including relativistic quantum information and spacetime.

We structured the workshop around the three workshop goals (i) QPV protocols and implementations, (ii) QPV and connections to foundational principles, (iii) Deep use case analysis, and in order to achieve these goals, we formed 3 working groups on the first day which will worked on the 3 closely related challenges. This has very successfully engaged all participants in a useful way, and paved the way for future collaborations, joint publications and grant applications. Another essential part of the workshop were the 3 tutorials where everybody had the chance to work on exciting problems around nonlocal quantum computation, but with the key experts sitting next to you - a very nice and useful experience for everybody.
