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 ...

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 ...
