About us
The Quantum Matter Interfaces Group (QMI) is an independent research group led by Johannes Zeiher at the Max-Planck-Institute of Quantum Optics. The work in the QMI Group is funded by the Quantum Futur Program of the BMBF within the project SNAQC. Since 2025, we are also located at the Ludwig Maximilians University of Munich (LMU) as part of the AG Synthetic Quantum Matter.

Coupling complex quantum systems to light is one of the fundamental challenges for all quantum technologies. Recent research has made spectacular advances in the bottom-up assembly of laser-cooled atoms to almost arbitrary configurations. In combination with strong, long-range interactions between Rydberg atoms, such atom arrays allow for realizing almost arbitrarily programmable quantum systems and for studying important models of quantum magnetism in a highly controlled setting. The experiments also fulfill all criteria to realize first quantum computing devices. Coupling single atoms strongly to optical resonators has been at the focus of experimental efforts for long times to realize strong light-matter interactions and couple elementary qubits to flying photons, which are for example required to transmit quantum information over large distances and to realize quantum networks.
Our independent research group will target the combination of highly controlled closed quantum systems coupled to Rydberg states with strong coupling to high-cooperativity optical resonators. This will allow for realizing novel models of many-body physics, studying the interplay between coherent quantum dynamics with controlled dissipation, and taking the first steps towards error-corrected logical qubits in Rydberg arrays. Our work will also explore approaches to optically interconnect atom arrays.
Opportunities and directions we are pursuing:
New methods to perform non-destructive measurements on quantum systems using optical resonators.
Feedback of measurement results on single atoms or groups of atoms.
Studying the complex interplay between Rydberg-induced and resonator-assisted interactions for quantum simulations.
Real-time readout of quantum systems for quantum metrology applications.
Dual-species arrays for non-destructive readout and quantum error correction applications.
Realization of logical qubits and optical interconnects in neutral-atom quantum computers.
