Secure Multi-party Quantum Computation with a Dishonest Majority
Yfke Dulek, Alex B. Grilo, Stacey Jeffery +2
The cryptographic task of secure multi-party (classical) computation has received a lot of attention in the last decades. Even in the extreme case where a computation is performed…
Non-malleability for quantum public-key encryption
Christian Majenz, Christian Schaffner, Jeroen van Wier
Non-malleability is an important security property for public-key encryption (PKE). Its significance is due to the fundamental unachievability of integrity and authenticity guarant…
Quantum Lazy Sampling and Game-Playing Proofs for Quantum Indifferentiability
Jan Czajkowski, Christian Majenz, Christian Schaffner +1
Game-playing proofs constitute a powerful framework for non-quantum cryptographic security arguments, most notably applied in the context of indifferentiability. An essential ingre…
Robust self-testing of two-qubit states
Tim Coopmans, Jędrzej Kaniewski, Christian Schaffner
It is well-known that observing nonlocal correlations allows us to draw conclusions about the quantum systems under consideration. In some cases this yields a characterisation whic…
