WG4 – Hybrid Systems
Leader Johannes Hecker Denschlag  • Vice-leader Michał Tomza 
The WG 4 - Hybrid Systems will concentrate on the task of advancing the experimental methods to couple trapped ions to other quantum systems, such as neutral atoms or optical cavities.
The objectives of this working group include implementation of new experimental approaches to study cooling, ion-neutral interactions, collisions and chemical reactions.
In addition, standardised designs, technologies and components for experiments of ions in optical cavities will be compiled and standard components will be shared.
Furthermore, other hybrid systems (such as ion-superconductor and ion-microwave systems) and their applications will be explored.
