Leon Karpa

Dr. Leon Karpa serves as a Group Leader at the Institute of Quantum Optics within the Faculty of Mathematics and Physics at Leibniz University Hannover. His research centers on experimental ultracold quantum systems, specializing in hybrid platforms combining ions with neutral atoms and molecules. Leading the Molecular Quantum Gases group, he develops advanced optical trapping techniques for quantum simulation and precision measurement applications, with facilities located at Welfengarten 1, Building 1101, Room D303 in Hanover.

His research interests focus on ultracold quantum gases, quantum optics, and atomic molecular optical physics, with specific expertise in ion-atom interactions, optical shielding of molecular collisions, and formation of ground-state molecules. The Molecular Quantum Gases group employs laser cooling, photoassociation, and microwave association techniques to control quantum states at nanokelvin temperatures, targeting applications in quantum information processing and fundamental chemistry studies.

Analysis of his 2020-2025 publications reveals three dominant research trajectories: (1) optical trapping of ion Coulomb crystals in lattice potentials, (2) formation and control of ultracold polar molecules, and (3) Feshbach resonance studies in ion-atom mixtures. These works collectively advance quantum simulation capabilities through precise manipulation of dipolar interactions and collision dynamics in hybrid quantum systems.

The Molecular Quantum Gases laboratory operates specialized infrastructure for optical dipole trapping, quantum state detection, and composite trap systems. Current experimental priorities include optical formation of NaK ground-state molecules, two-photon collision shielding protocols, and development of state-selective optical potentials for ion crystal manipulation, with direct relevance to quantum computing architectures.
