Quantum technologies exploit entanglement to revolutionize computing, measurements, and
communications. This has stimulated the research in different areas of physics to engineer …

Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …

In 1935, Einstein, Podolsky, and Rosen (EPR) conceived a gedanken experiment which
became a cornerstone of quantum technology and still challenges our understanding of …

Quantum scrambling describes the spreading of information into many degrees of freedom
in quantum systems, such that the information is no longer accessible locally but becomes …

Many-particle entanglement is a fundamental concept of quantum physics that still presents
conceptual challenges. Although nonclassical states of atomic ensembles were used to …

A key resource for distributed quantum-enhanced protocols is entanglement between
spatially separated modes. However, the robust generation and detection of entanglement …

Modern quantum technologies in the fields of quantum computing, quantum simulation, and
quantum metrology require the creation and control of large ensembles of entangled …

Einstein-Rosen-Podolsky (EPR) steering or quantum steering describes the “spooky action
at a distance” that one party is able to remotely alter the states of the other if they share a …

ABSTRACT A new type of quantum interferometer was recently realized that employs
parametric amplifiers (PAs) as the wave splitting and mixing elements. The quantum …

Entanglement is the key quantum resource for improving measurement sensitivity beyond
classical limits. However, the production of entanglement in mesoscopic atomic systems has …
