Nonlocality with Three and More Parties,In the precedent chapters, we focused on Bell-type experiments involving two parties only. While this is the simplest case, and indeed the most often discussed one, the idea of local correlations can be extended straightforwardly to multipartite scenarios involving more parties.

Quantum Information Put into Practice,Allowing information to be carried by physical systems described by the rules of quantum physics led to a deep questioning of the theory of information. While many questions remain open, the emerging field of quantum information already led to several remarkably concrete applications which would not exist otherwise.

Bell Tests in Bipartite Scenarios,ity and the detection loophole might soon be closable within the same experiment. In order to make this happen, novel proposals taking into account present capabilities are highly welcome. Here we describe a proposal for a loophole-free Bell test, and analyse its feasibility.

Various Quantum Nonlocality Tests with a Commercial Two-photon Entanglement Source,tion in which Bell inequalities can be measured has been proposed by Clauser- Horne-Shimony-Holt (CHSH). However, alternative nonlocality tests can also be carried out. In particular, Bell inequalities requiring multiple measurement settings can provide deeper fundamental insights about quantum nonl

Quantifying Multipartite Nonlocality,ficiently many parties broadcast their measurement inputs. The maximal number . of groups and the minimal number . of broadcasting parties that allow for the reproduction of a given set of correlations quantify their multipartite nonlocal content. We show how upper-bounds on . and lower-bounds on .

Device-Independent Entanglement Detection,ncatenation of the sate of each particle. Experimental demonstration of entanglement is generally performed with one of the two following techniques: tomography of the full quantum state, or evaluation of an entanglement witness.

Finite-Speed Hidden Influences,ences propagating slower than light. Yet, these correlations can still be explained in a causal manner if one gives up Bell’s locality condition. Indeed, this is the explanation followed when one says something like “A measurement on the singlet state . yielding result ‘0’ in the computational basis

Quantum Non-Locality Based on Finite-Speed Causal Influences Leads to Superluminal Signalling,l influences propagating at subluminal speed. Yet, any such experimental violation could always be explained in principle through models based on hidden influences propagating at a finite speed ., provided . is large enough.
