Jens Koch

Jens Koch is a Professor of Physics and Astronomy at Northwestern University, serving as Deputy Director of the SQMS (Stevenson Quantum Materials and Systems) and Co-Director of the CAPST (Center for Applied Physics and Superconducting Technologies). He holds a PhD from Freie Universität Berlin (2006) and specializes in theoretical condensed matter physics, focusing on quantum circuits, coherence in nanoscale systems, and quantum information processing. His research explores superconducting devices as artificial atoms in quantum computing and quantum optics, with collaborations on coherence studies and Josephson-junction-based circuits. He co-directs CAPST, advancing superconducting technologies for quantum applications.

Notable contributions include the development of fluxonium qubits and work on circuit quantum electrodynamics (cQED). His awards include the 2024 APS Fellowship. Koch's research bridges theoretical and experimental physics, addressing challenges in quantum error correction, noise mitigation, and scalable quantum systems. He collaborates across institutions to advance quantum simulators of strongly interacting photons and polaritonic systems. His work spans device design, control protocols, and computational tools like the scqubits Python package.

Key research areas include coherence enhancement in superconducting qubits, quantum control protocols, and hybrid quantum systems. His lab develops novel qubit architectures and investigates quantum phase transitions in lattice models. Koch’s contributions to quantum technology have been recognized through high-impact publications and leadership roles in quantum initiatives.
