The Grothendieck Game and Self-Testing Continuous Groups
Alexander Kulpe, Giulio Malavolta, Simon Schmidt +1
Self-testing certifies quantum states and measurements from observed correlations alone, without requiring a description of the devices that produce them. In this work we establish…
A commuting operator self-test for exact entanglement embezzlement
Connor Paddock, Simon Schmidt
We show that the optimal commuting operator correlation for a variant of Coladangelo's two-player generalized nonlocal game, based on the embezzlement of entanglement, is a commuti…
Guess your neighbor's input: Quantum advantage in Feige's game
Simon Schmidt, Sigurd A. L. Storgaard, Michael Walter +1
In this article, we study a nonlocal game with two questions and three answers per player, which was first considered by Feige in 1991, and show that there is quantum advantage in…
Quantitative Quantum Soundness for Bipartite Compiled Bell Games via the Sequential NPA Hierarchy
Igor Klep, Connor Paddock, Marc-Olivier Renou +4
Compiling Bell games under cryptographic assumptions replaces the need for physical separation, allowing nonlocality to be probed with a single untrusted device. While Kalai et al.…
A bound on the quantum value of all compiled nonlocal games
Alexander Kulpe, Giulio Malavolta, Connor Paddock +2
A cryptographic compiler introduced by Kalai et al. (STOC'23) converts any nonlocal game into an interactive protocol with a single computationally bounded prover. Although the com…
A Computational Tsirelson's Theorem for the Value of Compiled XOR Games
David Cui, Giulio Malavolta, Arthur Mehta +5
Nonlocal games are a foundational tool for understanding entanglement and constructing quantum protocols in settings with multiple spatially separated quantum devices. In this work…
