Matthias Schmelz

Matthias Schmelz is a researcher at the Leibniz Institute of Photonic Technology, working in the Quantum Circuits group under the Research Department Quantum Systems. His work focuses on the development of superconducting quantum circuits and cryogenic electronics, with a particular emphasis on Josephson junction fabrication, SQUID-based readout systems, and wafer-scale integration for scalable quantum technologies.

Key research contributions include the design of adiabatic quantum flux parametrons (AQFP), development of high-inductance cryogenic current comparators (CCC), and optimization of microwave SQUID multiplexer (µMUX) architectures for terahertz security cameras. His projects involve collaborations with institutions like CERN and GSI Darmstadt, addressing challenges in millikelvin thermalization, noise reduction, and quantum device characterization.

Recent publications highlight advancements in cross-type Josephson junction fabrication, controllable mode coupling in coplanar waveguides, and hybrid NbN-Al quantum technologies. These works span journals including Physical Review B and IEEE Transactions on Applied Superconductivity, with applications in quantum computing, particle beam diagnostics, and high-sensitivity optical sensor readouts.
