Detecting bipartite entanglement with PnCP maps and non-negative polynomials
Gaël Massé, Mounir Rezig, Paul Catala +4
Positive non-Completely Positive (PnCP) maps are an essential tool to detect entanglement since their characterization is a dual aspect of the separability problem. A recent algori…
Long-range photonic device-independent quantum key distribution using SPDC sources and linear optics
Morteza Moradi, Maryam Afsary, Piotr Mironowicz +2
We address the question of the implementation of long-distance device-independent quantum key distribution (DI QKD) by proposing two experimentally viable schemes. Those schemes on…
A unified framework for Bell inequalities from continuous-variable contextuality
Carlos Ernesto Lopetegui-González, Gaël Massé, Enky Oudot +6
Although the original EPR paradox was formulated in terms of position and momentum, most studies of these phenomena have focused on measurement scenarios with only a discrete numbe…
Long-distance device-independent quantum key distribution using single-photon entanglement
Anna Steffinlongo, Mariana Navarro, Marina Cenni +3
Device-independent quantum key distribution (DIQKD) provides the strongest form of quantum security, as it allows two honest users to establish secure communication channels even w…
