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 ...

Irreducible magic sets for n-Qubit systems
(Physical Review Letters, 2022-11-07)
Magic sets of observables are minimal structures that capture quantum state-independent advantage for systems of n ≥ 2 qubits and are, therefore, fundamental tools for investigating the interface between classical and ...

Quantum contextuality provides communication complexity advantage
(American Physical Society, 2023-02-24)
Despite the conceptual importance of contextuality in quantum mechanics, there is a hitherto limited number of applications requiring contextuality but not entanglement. Here, we show that for any quantum state and observables ...

Graph-theoretic approach to Bell experiments with low detection efficiency
(Cornell University, 2023)
Bell inequality tests where the detection efficiency is below a certain threshold ηcrit can be simulated with local hidden-variable models. For the Clauser-Horne-Shimony-Holt Bell inequality and maximally entangled states, ...

A comparison of 210Pbxs, 137Cs, and Pu isotopes as proxies of soil redistribution in South Spain under severe erosion conditions
(Springer, 2023-06-01)
Purpose The use of fallout radionuclides as proxies for the study of soil redistribution processes in semiarid environments of Southern Spain has been restricted to 137Cs. The potential and limitations of alternative ...
