A complexity theory for non-local quantum computation
Andreas Bluhm, Simon Höfer, Alex May +3
Non-local quantum computation (NLQC) replaces a local interaction between two systems with a single round of communication and shared entanglement. Despite many partial results, it…
Equivalence of non-local computation tasks beyond Clifford operations
Andreas Bluhm, Simon Höfer, Alex May +2
Non-local quantum computation (NLQC) studies how two collaborating players can implement channels on distributed systems using a single simultaneous round of quantum communication…
Device independent quantum key distribution with robust self-tests
Andreas Bluhm, Gereon KoÃmann, René Schwonnek
Device-independent quantum key distribution (DIQKD) provides a model of quantum key distribution with minimal assumptions and highly abstract theoretical building blocks. Although…
Learning Coulomb Potentials and Beyond with Free Fermions in Continuous Space
Andreas Bluhm, Marius Lemm, Tim Möbus +1
The first-principles formulation of quantum mechanics relevant for quantum chemistry and trapped quantum gases involves particles in the continuous space . We present…
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…
