Machine learning meets quantum foundations: A brief survey
The goal of machine learning is to facilitate a computer to execute a specific task without
explicit instruction by an external party. Quantum foundations seek to explain the conceptual …

Full network nonlocality
Networks have advanced the study of nonlocality beyond Bell's theorem. Here, we introduce
the concept of full network nonlocality, which describes correlations that necessitate all links …

The inflation technique for causal inference with latent variables
The problem of causal inference is to determine if a given probability distribution on
observed variables is compatible with some causal structure. The difficult case is when the …

Entanglement swapping and quantum correlations via symmetric joint measurements
We use hyperentanglement to experimentally realize deterministic entanglement swapping
based on quantum elegant joint measurements. These are joint projections of two qubits …

Experimental nonclassicality in a causal network without assuming freedom of choice
In a Bell experiment, it is natural to seek a causal account of correlations wherein only a
common cause acts on the outcomes. For this causal structure, Bell inequality violations can …

Bilocal Bell inequalities violated by the quantum elegant joint measurement
Network Bell experiments give rise to a form of quantum nonlocality that conceptually goes
beyond Bell's theorem. We investigate here the simplest network, known as the bilocality …

Quantifying Bell: The resource theory of nonclassicality of common-cause boxes
We take a resource-theoretic approach to the problem of quantifying nonclassicality in Bell
scenarios. The resources are conceptualized as probabilistic processes from the setting …

Semidefinite programming relaxations for quantum correlations
Semidefinite programs are convex optimisation problems involving a linear objective
function and a domain of positive semidefinite matrices. Over the last two decades, they …
