Probabilistic theories stable under teleportation
Lionel J. Dmello, David Gross
A long-standing problem in the foundations of quantum mechanics is to identify a physical principle that explains why algebraically maximal violations of Bell inequalities can gene…

Entanglement-swapping in generalised probabilistic theories, and iterated CHSH games
Lionel J. Dmello, Laurens T. Ligthart, David Gross
While there exist theories that have states "more strongly entangled" than quantum theory, in the sense that they show CHSH values above Tsirelson's bound, all known examples of su…
