Entanglement in prepare-and-measure scenarios: many questions, a few answers
New Journal of Physics, 2022 Entanglement and quantum communication are paradigmatic resources in quantum information science leading to correlations between systems that have no classical analogue.

Optimal randomness generation from optical Bell experiments [PDF]
, 2014 Genuine randomness can be certified from Bell tests without any detailed assumptions on the working of the devices with which the test is implemented. An important class of experiments for implementing such tests is optical setups based on polarisation ...

A histories perspective on characterizing quantum non-locality
New Journal of Physics, 2014 We introduce a framework for studying non-locality and contextuality inspired by the path integral formulation of quantum theory. We prove that the existence of a strongly positive joint quantum measure—the quantum analogue of a joint probability measure—

Sum-of-squares decompositions for a family of Clauser-Horne-Shimony-Holt-like inequalities and their application to self-testing [PDF]
, 2015 We introduce two families of sum-of-squares (SOS) decompositions for the Bell operators associated with the tilted Clauser-Horne-Shimony-Holt (CHSH) expressions introduced in Acin et al. [Phys. Rev. Lett. 108, 100402 (2012)].

, 2009 Device independent quantum key distribution aims to provide a higher degree of security than traditional QKD schemes by reducing the number of assumptions that need to be made about the physical devices used.

Quantifying multipartite nonlocality via the size of the resource [PDF]
, 2014 The generation of (Bell-)nonlocal correlations, i.e., correlations leading to the violation of a Bell-like inequality, requires the usage of a nonlocal resource, such as an entangled state.

, 2014 The correlations that admit a local hidden-variable model are described by a family of polytopes, whose facets are the Bell inequalities. The CHSH inequality is the simplest such Bell inequality and is a facet of every Bell polytope.

More randomness from noisy sources [PDF]
, 2014 Bell experiments can be used to generate private random numbers. An ideal Bell experiment would involve measuring a state of two maximally entangled qubits, but in practice any state produced is subject to noise.
