Semidefinite programming relaxations for quantum correlations

A Tavakoli, A Pozas-Kerstjens, P Brown… - Reviews of Modern Physics, 2024 - APS
Semidefinite programs are convex optimization problems involving a linear objective
function and a domain of positive-semidefinite matrices. Over the past two decades, they …

Estimating the volume of correlation sets in causal networks

G Camillo, P Lauand, D Poderini, R Rabelo, R Chaves - Physical Review A, 2024 - APS
Causal networks beyond that in the paradigmatic Bell's theorem can lead to new kinds and
applications of nonclassical behavior. Their study, however, has been hindered by the fact …

Hierarchical certification of nonclassical network correlations

MX Luo, X Yang, A Pozas-Kerstjens - Physical Review A, 2024 - APS
With the increased availability of quantum technological devices, it becomes more important
to have tools to guarantee their correct nonclassical behavior. This is especially important for …

Quantum non-classicality in the simplest causal network

P Lauand, D Poderini, R Rabelo, R Chaves - ar** the Shadow of Bell's Theorem in Network Nonlocality
M Ciudad-Alañón, EC Boghiu, P Abiuso… - arxiv preprint arxiv …, 2024 - arxiv.org
The possibility of nonclassicality in networks unrelated to Bell's original eponymous theorem
has recently attracted significant interest. Here, we identify a sufficient condition for being" …

Study of Bell Nonlocality in the Minimal Triangle Scenario

M Viner Tesoriere - 2024 - diposit.ub.edu
The study of quantum networks continues to prove its value both in practical and theoretical
applications. Among these networks, one of the simplest to consider is the minimal triangle …
