Jonas Bundgaard Mathiassen

Jonas Bundgaard Mathiassen is a Guest Researcher at the Niels Bohr Institute within the Faculty of Science at the University of Copenhagen. His research focuses on quantum photonics and optomechanics, specializing in photonic crystal devices for quantum applications with cold atoms and cavity systems.

He recently completed his PhD at the University of Copenhagen in 2024. His doctoral dissertation, titled 'Design and Fabrication of Suspended Si3N4 Photonic Crystal Devices For Use With Cold Atoms', addressed nanofabrication challenges for quantum technologies using silicon nitride photonic structures.

Mathiassen's work bridges quantum optics, atomic physics, and condensed matter physics. He develops photonic crystal membranes for quantum optomechanics, with emphasis on phononic engineering to suppress thermal noise. His expertise includes nanofabrication techniques, cavity quantum electrodynamics, and quantum interface design for cold atom systems.

His 2023 publication in Optics Express on phononically shielded mirror membranes demonstrates innovative approaches to enhance quantum coherence in optomechanical systems. This research contributes to advancing quantum sensing platforms and quantum network interfaces through precision control of light-matter interactions.
