Quantitative quantum soundness for all multipartite compiled nonlocal games
Matilde Baroni, Igor Klep, Dominik Leichtle +4
Compiled nonlocal games transfer the power of Bell-type multi-prover tests into a single-device setting by replacing spatial separation with cryptography. Concretely, the KLVY comp…
Composable simultaneous purification: when all communication scenarios reduce to spatial correlations
Matilde Baroni, Dominik Leichtle, Ivan Å upiÄ +2
Bell non-locality is a powerful framework to distinguish classical, quantum and post-quantum resources, which relies on non-communicating players. Under which restriction can we ha…
Experimental Quantum Electronic Voting
Nicolas Laurent-Puig, Matilde Baroni, Federico Centrone +1
Quantum information protocols offer significant advantages in properties such as security, anonymity, and privacy for communication and computing tasks. An application where guaran…
Quantum bounds for compiled XOR games and -outcome CHSH games
Matilde Baroni, Quoc-Huy Vu, Boris Bourdoncle +3
Nonlocal games play a crucial role in quantum information theory and have numerous applications in certification and cryptographic protocols. Kalai et al. (STOC 2023) introduced a…
Bounding the asymptotic quantum value of all multipartite compiled non-local games
Matilde Baroni, Dominik Leichtle, SiniÅ¡a JankoviÄ +1
Non-local games are a powerful tool to distinguish between correlations possible in classical and quantum worlds. Kalai et al. (STOC'23) proposed a compiler that converts multipart…
Translating Bell Non-Locality to Prepare-and-Measure Scenarios under Dimensional Constraints
Matilde Baroni, Eleni Diamanti, Damian Markham +1
Understanding the connections between different quantum information protocols has been proven fruitful for both theoretical insights and experimental applications. In this work, we…
