NPA Hierarchy and Extremal Criterion in the Simplest Bell Scenario [PDF]

Entropy
It is difficult to establish an analytical criterion to identify the boundaries of quantum correlations, even for the simplest Bell scenario. Here, we briefly reviewed the plausible analytical criterion, and we found a way to confirm the extremal ...

Bell nonlocality [PDF]

, 2014
Bell's 1964 theorem, which states that the predictions of quantum theory cannot be accounted for by any local theory, represents one of the most profound developments in the foundations of physics.

Simulation of equatorial von Neumann measurements on GHZ states using nonlocal resources [PDF]

Advances in Mathematical Physics, Volume 2010, Issue 1, 2010., 2010
Reproducing with elementary resources the correlations that arise when a quantum system is measured (quantum state simulation), allows one to get insight on the operational and computational power of quantum correlations.

Beyond Bell's theorem: correlation scenarios [PDF]

New Journal of Physics, 2012
Bell's theorem witnesses that the predictions of quantum theory cannot be reproduced by theories of local hidden variables in which observers can choose their measurements independently of the source.

Using complete measurement statistics for optimal device-independent randomness evaluation

New Journal of Physics, 2014
The majority of recent works investigating the link between non-locality and randomness, e.g. in the context of device-independent cryptography, do so with respect to some specific Bell inequality, usually the CHSH inequality.

Information capacity of quantum communication under natural physical assumptions [PDF]

Quantum
The quantum prepare-and-measure scenario has been studied under various physical assumptions on the emitted states. Here, we first discuss how different assumptions are conceptually and formally related.

Joint-measurability and quantum communication with untrusted devices [PDF]

Quantum
Photon loss represents a major challenge for the implementation of quantum communication protocols with untrusted devices, e.g. in the device-independent (DI) or semi-DI approaches.

Semi-device-independent framework based on natural physical assumptions [PDF]

Quantum, 2017
The semi-device-independent approach provides a framework for prepare-and-measure quantum protocols using devices whose behavior must not be characterized nor trusted, except for a single assumption on the dimension of the Hilbert space characterizing ...

Device-independent bit commitment based on the CHSH inequality

New Journal of Physics, 2016
Bit commitment and coin flipping occupy a unique place in the device-independent landscape, as the only device-independent protocols thus far suggested for these tasks are reliant on tripartite GHZ correlations.
