We develop a resource-theoretical approach that allows us to quantify values of two-player, one-round cooperative games with quantum inputs and outputs, as well as values of quantum probabilistic hypergraphs. We analyse the quantum game values arising from the type hierarchy of quantum no-signalling correlations, establishing tensor norm expressions for each of the correlation types. As a consequence, we provide metric characterisations of state convertibility via LOSR and LOCC.En route, we obtain an alternative description of the maximal tensor products of ternary rings of operators.

  1. An operator system approach to self-testing

    quant-ph 2025-06 conditional novelty 8.0 of 10

    Self-testing in the commuting operator model is defined operationally via local isometries between operator-system models, unifying POVM, QNS, contextuality, colouring and Schur-channel self-tests.
