Bell's theorem proves that quantum theory is inconsistent with local physical models. It has
propelled research in the foundations of quantum theory and quantum information science …

A violation of Bell-CHSH inequalities does not justify speculations about quantum non-
locality, conspiracy and retro-causation. Such speculations are rooted in a belief that setting …

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

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 …

Quantum networks are the center of many of the recent advances in quantum science, not
only leading to the discovery of new properties in the foundations of quantum theory but also …

Quantum networks promise unprecedented advantages in information processing and open
up intriguing new opportunities in fundamental research, where network topology and …

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 …

When should a given operational phenomenology be deemed to admit of a classical
explanation? When it can be realized in a generalized-noncontextual ontological model …

We investigate network nonlocality in the triangle scenario when all three parties have no
input and binary outputs. Through an explicit example, we prove that this minimal scenario …

The violation of a Bell inequality is the paradigmatic example of device-independent
quantum information: The nonclassicality of the data is certified without the knowledge of the …
