Self-testing of a single quantum system from theory to experiment
(Nature Research, 2023-10-19)
Self-testing allows one to characterise quantum systems under minimal assumptions. However, existing schemes rely on quantum nonlocality and cannot be applied to systems that are not entangled. Here, we introduce a robust ...

General Bayesian theories and the emergence of the exclusivity principle
(American Physical Society, 2020-10-05)
We address the problem of reconstructing quantum theory from the perspective of an agent who makes bets about the outcomes of possible experiments. We build a general Bayesian framework that can be used to organize the ...

Certifying sets of quantum observables with any full-rank state
(American Physical Society, 2024-04-03)
We show that some sets of quantum observables are unique up to an isometry and have a contextuality witness that attains the same value for any initial state. We prove that these two properties make it possible to certify ...
