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…

Sinkhorn algorithm for quantum permutation groups
Ion Nechita, Simon Schmidt, Moritz Weber
We introduce a Sinkhorn-type algorithm for producing quantum permutation matrices encoding symmetries of graphs. Our algorithm generates square matrices whose entries are orthogona…

Existence of quantum symmetries for graphs on up to seven vertices: a computer based approach
Christian Eder, Viktor Levandovskyy, Julien Schanz +3
The symmetries of a finite graph are described by its automorphism group; in the setting of Woronowicz's quantum groups, a notion of a quantum automorphism group has been defined b…
