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 …

Entangled photon sources are desirable and key elements for photonic quantum information
processing. The spontaneous parametric down‐conversion (SPDC) process is a convenient …

Although complex numbers are essential in mathematics, they are not needed to describe
physical experiments, as those are expressed in terms of probabilities, hence real numbers …

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 …

Quantum information technologies provide promising applications in communication and
computation, while machine learning has become a powerful technique for extracting …

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 …

Networks composed of independent sources of entangled particles that connect distant
users are a rapidly develo** quantum technology and an increasingly promising test-bed …

Quantum networks play a major role in long-distance communication, quantum
cryptography, clock synchronization, and distributed quantum computing. Generally, these …

The launch of a satellite capable of distributing entanglement through long distances and
the first loophole-free violation of Bell inequalities are milestones indicating a clear path for …

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 …
