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 ...

Maximum nonlocality in the (3,2,2) scenario
(American Physical Society, 2016-12-27)
We identify the simplest combinations of entanglement and incompatibility giving the maximum quantum violation for each of the 46 classes of tight Bell inequalities for the (3,2,2) scenario, i.e., three parties, two ...

Significant loophole-free test of Kochen-Specker contextuality using two species of atomic ions
(American Association for the Advancement of Science, 2022-02-09)
Quantum measurements cannot be thought of as revealing preexisting results, even when they do not disturb any other measurement in the same trial. This feature is called contextuality and is crucial for the quantum advantage ...

Geometric driving of two-level quantum systems
(American Physical Society, 2020)
We investigate a class of cyclic evolutions for driven two-level quantum systems (effective spin 1/2) with a particular focus on the geometric characteristics of the driving and their specific imprints on the quantum ...

Experimental test of quantum correlations from Platonic graphs
(Optica Publishing Group, 2018-05-29)
Great effort has been made in the investigation of contextual correlations between compatible observables due to their both fundamental and practical importance. The graph-theoretic approach to correlate events has been ...

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 ...
