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

We review methods that allow one to detect and characterize quantum correlations in many-
body systems, with a special focus on approaches which are scalable. Namely, those …

Quantum-photonic chips, which integrate quantum light sources alongside active and
passive optical elements, as well as single-photon detectors, show great potential for …

Quantum mechanics is now a mature topic dating back more than a century. During its
scientific development, it fostered many technological advances that now are integrated into …

The existence of better-than-classical quantum information processing (QIP) models which
consume very little or no entanglement suggests that separable or weakly entangled states …

One of the greatest challenges in the fields of quantum information processing and quantum
technologies is the detailed coherent control over each and every constituent of quantum …

Entanglement-enhanced quantum metrology explores the utilization of quantum
entanglement to enhance measurement precision. When particles in a probe are prepared …

Generating and detecting genuine multipartite entanglement (GME) of sizeable quantum
states prepared on physical devices is an important benchmark for highlighting the progress …

We derive laws for the distribution of quantum steering among different parties in multipartite
Gaussian states under Gaussian measurements. We prove that a monogamy relation akin to …

Intensive studies of entanglement properties have proven essential for our understanding of
quantum many-body systems. In contrast, much less is known about the role of quantum …
