Creating heralded hyper-entangled photons using Rydberg atoms
Light: Science & Applications, 2021 Entangled photon pairs are a fundamental component for testing the foundations of quantum mechanics, and for modern quantum technologies such as teleportation and secured communication.

Pattern formation of quantum jumps with Rydberg atoms [PDF]
, 2012 We study the nonequilibrium dynamics of quantum jumps in a one-dimensional chain of atoms. Each atom is driven on a strong transition to a short-lived state and on a weak transition to a metastable state.

Lifetimes of ultralong-range Rydberg molecules in vibrational ground and excited state
, 2011 Since their first experimental observation, ultralong-range Rydberg molecules consisting of a highly excited Rydberg atom and a ground state atom have attracted the interest in the field of ultracold chemistry.

Exotic Chemistry with Ultracold Rydberg Atoms
CHIMIA, 2016 We review recent experiments carried out with dense (1012 cm–3) ultracold (T = 40 ?K) samples of Cs atoms which have the goal to characterize, by high-resolution spectroscopy, the interactions between Cs atoms, Cs+ ions and electrons that lead to the formation of metastable long-range molecules.

Rydberg atoms in astrophysics [PDF]
New Astronomy Reviews, 2009 Elementary processes in astrophysical phenomena traditionally attract researchers attention. At first this can be attributed to a group of hemi-ionization processes in Rydberg atom collisions with ground state parent atoms. This processes might be studied as a prototype of the elementary process of the radiation energy transformation into electrical ...

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.A tool to model ensemble‐based atomic quantum memory experiments using the quantum channel formalism is presented, incorporating realistic loss and noise effects. It provides a digital twin of state‐of‐the‐art memories and demonstrates its applicability through a simulation of a memory‐assisted quantum token protocol. The framework is easily extendable

Dipolar Rydberg-atom gas prepared by adiabatic passage through an avoided crossing
New Journal of Physics, 2015 The passage of cold cesium 49S $_{1/2}$ Rydberg atoms through an electric-field-induced multi-level avoided crossing with nearby hydrogen-like Rydberg levels is employed to prepare a cold, dipolar Rydberg atom gas.

Collective Quantum Jumps of Rydberg Atoms
Physical Review Letters, 2012 We study an open quantum system of atoms with long-range Rydberg interaction, laser driving, and spontaneous emission. Over time, the system occasionally jumps between a state of low Rydberg population and a state of high Rydberg population. The jumps are inherently collective and in fact exist only for a large number of atoms.

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.Alle Seltenerdelemente bilden bekanntlich tri‐ und auch di‐valente Verbindungen. Wenige tetra‐valente Verbindungen sind auch bekannt; kürzlich wurden die ersten Moleküle und Kristalle mit Praseodym(+5) synthetisiert. Der hier definierte atomare Ionisations‐Quotient IQ legt nahe, dass Ln(+4)‐Verbindungen mit geeigneten Liganden für fast alle 4f‐Elemente

Rydberg-Rydberg interaction profile from the excitation dynamics of ultracold atoms in lattices
, 2011 We propose a method for the determination of the interaction potential of Rydberg atoms. Specifically, we consider a laser-driven Rydberg gas confined in a one-dimensional lattice and demonstrate that the Rydberg atom number after a laser excitation ...
