Towards practical quantum position verification
George Cowperthwaite, Adrian Kent, Damian Pitalua-Garcia
We discuss protocols for quantum position verification schemes based on the standard quantum cryptographic assumption that a tagging device can keep classical data secure [Kent, 20…
Testing the nonclassicality of spacetime: what can we learn from Bell-Bose et al.-Marletto-Vedral experiments?
Adrian Kent, Damián Pitalúa-García
The Bose et al.-Marletto-Vedral (BMV) experiment [S. Bose et al., Phys. Rev. Lett. 119, 240401 (2017); C. Marletto and V. Vedral, Phys. Rev. Lett. 119, 240402 (2017)] aims to prove…
Unconditionally secure relativistic multi-party biased coin flipping and die rolling
Damián Pitalúa-García
We introduce relativistic multi-party biased die rolling protocols, generalizing coin flipping to parties and to outcomes for any chosen outcome biases, and s…
Quantum information causality
Damián Pitalúa-García
How much information can a transmitted physical system fundamentally communicate? We introduce the principle of quantum information causality, which states the maximum amount of qu…
