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…
Efficient NIZKs and Signatures from Commit-and-Open Protocols in the QROM
Jelle Don, Serge Fehr, Christian Majenz +1
Commit-and-open Sigma-protocols are a popular class of protocols for constructing non-interactive zero-knowledge arguments and digital-signature schemes via the Fiat-Shamir transfo…
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…
A Guide for New Program Committee Members at Theoretical Computer Science Conferences
Yfke Dulek, Stacey Jeffery, Christian Majenz +3
In theoretical computer science, conferences play an important role in the scientific process. The decisions whether to accept or reject articles is taken by the program committee…
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…
Online-Extractability in the Quantum Random-Oracle Model
Jelle Don, Serge Fehr, Christian Majenz +1
We show the following generic result. Whenever a quantum query algorithm in the quantum random-oracle model outputs a classical value that is promised to be in some tight relat…
