Device-independent quantum key distribution based on Bell inequalities with more than two inputs and two outputs
(American Physical Society, 2021-05-28)
Device-independent quantum key distribution (DI-QKD) offers the strongest form of security against eavesdroppers bounded by the laws of quantum mechanics. However, a practical implementation is still pending due to the ...

Bell non-locality and Kochen-Specker contextuality: how are they connected?
(Springer, 2021-05-22)
Bell non-locality and Kochen–Specker (KS) contextuality are logically independent concepts, fuel different protocols with quantum vs classical advantage, and have distinct classical simulation costs. A natural question is ...

Optimal and tight Bell inequalities for state-independent contextuality sets
(American Physical Society, 2023)
Two fundamental quantum resources, nonlocality and contextuality, can be connected through Bell inequalities that are violated by state-independent contextuality (SI-C) sets. These Bell inequalities allow for applications ...
