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 ...

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 ...

Exponentially decreasing critical detection efficiency for any Bell inequality
(American Physical Society, 2022-11-30)
We address the problem of closing the detection efficiency loophole in Bell experiments, which is crucial for real-world applications. Every Bell inequality has a critical detection efficiency η that must be surpassed to ...
