Making Existing Quantum Position Verification Protocols Secure Against Arbitrary Transmission Loss
Rene Allerstorfer, Andreas Bluhm, Harry Buhrman +4
Signal loss poses a significant threat to the security of quantum cryptography when the chosen protocol lacks loss-tolerance. In quantum position verification (QPV) protocols, even…
Monogamy of highly symmetric states
Rene Allerstorfer, Matthias Christandl, Dmitry Grinko +4
We investigate the extent to which two particles can be maximally entangled when they are also similarly entangled with other particles on a complete graph, focusing on Werner, iso…
Security of a Continuous-Variable based Quantum Position Verification Protocol
Rene Allerstorfer, Llorenç Escolà-Farràs, Arpan Akash Ray +3
In this work we study quantum position verification with continuous-variable quantum states. In contrast to existing discrete protocols, we present and analyze a protocol that util…
Relating non-local quantum computation to information theoretic cryptography
Rene Allerstorfer, Harry Buhrman, Alex May +2
Non-local quantum computation (NLQC) is a cheating strategy for position-verification schemes, and has appeared in the context of the AdS/CFT correspondence. Here, we connect NLQC…
