Matroid isomorphism games
Daniel Corey, Simon Schmidt, Marcel Wack
We define and study a collection of matroid isomorphism games corresponding to various axiomatic characterizations of matroids. These are nonlocal games played between two cooperat…
Polytope compatibility -- from quantum measurements to magic squares
Andreas Bluhm, Ion Nechita, Simon Schmidt
Several central problems in quantum information theory (such as measurement compatibility and quantum steering) can be rephrased as membership in the minimal matrix convex set corr…
Quantum isomorphic strongly regular graphs from the root system
Simon Schmidt
In this article, we give a first example of a pair of quantum isomorphic, non-isomorphic strongly regular graphs, that is, non-isomorphic strongly regular graphs having the same ho…
Solution group representations as quantum symmetries of graphs
David Roberson, Simon Schmidt
In 2019, Aterias et al. constructed pairs of quantum isomorphic, non-isomorphic graphs from linear constraint systems. This article deals with quantum automorphisms and quantum iso…
Quantum symmetry vs nonlocal symmetry
David E. Roberson, Simon Schmidt
We introduce the notion of nonlocal symmetry of a graph , defined as a winning quantum correlation for the -automorphism game that cannot be produced classically. Recent conn…
Uniformly vertex-transitive graphs
Simon Schmidt, Chase Vogeli, Moritz Weber
We introduce uniformly vertex-transitive graphs as vertex-transitive graphs satisfying a stronger condition on their automorphism groups, motivated by a problem which arises from a…
