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…

Limit of Gaussian operations and measurements for Gaussian state discrimination, and its application to state comparison
David E. Roberson, Shuro Izumi, Wojciech Roga +3
We determine the optimal method of discriminating and comparing quantum states from a certain class of multimode Gaussian states and their mixtures when arbitrary global Gaussian o…

Graph isomorphism: Physical resources, optimization models, and algebraic characterizations
Laura Mančinska, David E. Roberson, Antonios Varvitsiotis
In the -isomorphism game, a verifier interacts with two non-communicating players (called provers) by privately sending each of them a random vertex from either or ,…
