Single-qubit detection by collective phase imprinting
Kritsana Srakaew, Pascal Weckesser, Daniel Adler +4
The amplification of quantum information carried by a single quantum excitation is a recurring challenge across diverse quantum platforms. The coupling between a single qubit and a…
Competing excitation quenching and charge exchange in ultracold Li-Ba collisions
Xiaodong Xing, Pascal Weckesser, Fabian Thielemann +9
Hybrid atom-ion systems are a rich and powerful platform for studying chemical reactions, as they feature both excellent control over the electronic state preparation and readout a…
Rydberg molecules bound by strong light fields
Simon Hollerith, Valentin Walther, Kritsana Srakaew +6
The coupling of an isolated quantum state to a continuum is typically associated with decoherence and decreased lifetime. Here, we demonstrate that Rydberg macrodimers, weakly boun…
A subwavelength atomic array switched by a single Rydberg atom
Kritsana Srakaew, Pascal Weckesser, Simon Hollerith +4
Enhancing light-matter coupling at the level of single quanta is essential for numerous applications in quantum science. The cooperative optical response of subwavelength atomic ar…
Optical trapping of ion Coulomb crystals
Julian Schmidt, Alexander Lambrecht, Pascal Weckesser +3
The electronic and motional degrees of freedom of trapped ions can be controlled and coherently coupled on the level of individual quanta. Assembling complex quantum systems ion by…
Long lifetimes in optical ion traps
Alexander Lambrecht, Julian Schmidt, Pascal Weckesser +3
We report on single Barium ions confined in a near-infrared optical dipole trap for up to three seconds in absence of any radio-frequency fields. Additionally, the lifetime in a vi…
