More is Less:Optimal Security for Haar Quantum Money and More
Zihan Hao, Xingjian Li, Qipeng Liu +1
Quantum cryptography leverages unclonability to enable a wide range of cryptographic applications that are impossible classically, such as digital currency protected against counte…
Parallel Quantum Advantage with Limited Adaptivity Requires Structure
Qipeng Liu, Saachi Mutreja
Aaronson and Ambainis (Theory of Computing, 2014) conjectured that quantum query algorithms admit efficient almost-everywhere classical simulation: for any -query quantum algori…
Unclonable encryption from BB84 states: a simultaneous Goldreich-Levin reduction
Andrea Coladangelo, Qipeng Liu, Ziyi Xie
Goldreich-Levin reductions are ubiquitous in cryptography: they convert an algorithm capable of guessing (mod ) for a hidden string and a random chall…
Impossibility of Perfectly Complete Many-Round Key Agreement in the QROM
Longcheng Li, Qian Li, Xingjian Li +1
This paper proves that it is impossible to construct perfectly complete quantum key agreement protocols (QKA) from quantumly secure one-way functions (OWFs) in a black-box manner.…
