Towards experimental demonstration of quantum position verification using true single photons
Kirsten Kanneworff, Mio Poortvliet, Dirk Bouwmeester +6
The geographical position can be a good credential for authentication of a party, this is the basis of position-based cryptography - but classically this cannot be done securely wi…
Continuous-variable Quantum Position Verification secure against entangled attackers
Rene Allerstorfer, Llorenç Escolà-Farràs, Arpan Akash Ray +2
Motivated by the fact that coherent states may offer practical advantages it was recently shown that a continuous-variable (CV) quantum position verification (QPV) protocol using c…
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…
Orthogonality Broadcasting and Quantum Position Verification
Ian George, Rene Allerstorfer, Philip Verduyn Lunel +1
The no-cloning theorem leads to information-theoretic security in various quantum cryptographic protocols. However, this security typically derives from a possibly weaker property…
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…
On the Role of Quantum Communication and Loss in Attacks on Quantum Position Verification
Rene Allerstorfer, Harry Buhrman, Florian Speelman +1
We study the role of quantum communication in attacks on quantum position verification. In this work, we construct the first known example of a QPV protocol that is provably secure…
Towards practical and error-robust quantum position verification
Rene Allerstorfer, Harry Buhrman, Florian Speelman +1
Loss of inputs can be detrimental to the security of quantum position verification (QPV) protocols, as it may allow attackers to not answer on all played rounds, but only on those…
