Lifting the maximally-entangledness assumption in robust self-testing for synchronous games
Matthijs Vernooij, Yuming Zhao
Robust self-testing in non-local games allows a classical referee to certify that two untrustworthy players are able to perform a specific quantum strategy up to high precision. Pr…

Robust self-testing for nonlocal games with robust game algebras
Yuming Zhao
We give an operator-algebraic formulation of robust self-testing in terms of states on C*-algebras. We show that a quantum correlation p is a robust self-test only if among all (ab…
