Parallel repetition of local simultaneous state discrimination
Llorenç Escolà-Farràs, Jaròn Has, Maris Ozols +2
Local simultaneous state discrimination (LSSD) is a recently introduced problem in quantum information processing. Its classical version is a non-local game played by non-communica…
Local simultaneous state discrimination
Christian Majenz, Maris Ozols, Christian Schaffner +1
Quantum state discrimination is one of the most fundamental problems studied in quantum information theory. Applications range from channel coding to metrology and cryptography. In…
Limitations on Uncloneable Encryption and Simultaneous One-Way-to-Hiding
Christian Majenz, Christian Schaffner, Mehrdad Tahmasbi
We study uncloneable quantum encryption schemes for classical messages as recently proposed by Broadbent and Lord. We focus on the information-theoretic setting and give several li…
Impossibility of Quantum Virtual Black-Box Obfuscation of Classical Circuits
Gorjan Alagic, Zvika Brakerski, Yfke Dulek +1
Virtual black-box obfuscation is a strong cryptographic primitive: it encrypts a circuit while maintaining its full input/output functionality. A remarkable result by Barak et al.…
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…
