Quantum Technology

University of Vienna

I am a postdoctoral researcher at the Faculty of Physics, University of Vienna, working with Prof. Markus Arndt. My current research is an experimental study of biomolecule interferometry using the optical near-field Talbot–Lau effect. My PhD thesis focused on matter-wave scattering (4He and D2) from surfaces at extremely small incidence angles, a regime that accesses a kinetic-energy range of 2–100 neV and lets us probe the atom-surface dispersion potential directly. That work demonstrated two classical optical principles — Babinet’s principle and the reciprocity theorem — in the matter-wave context, and uncovered a new non-destructive reflection mechanism: multiple edge-diffraction reflection.

Andrew Byun (변우정:Woojeong Byun) is a postdoc in Wolfgang Lechner's group at the University of Innsbruck. He holds a BS from Hanyang University and a PhD from KAIST. During his PhD, he worked on implementing quantum computing with a Rydberg atom array, particularly by adding additional atoms to generate all-to-all connectivity (Quantum wire). He moved to Korea University as a postdoc and studied the ytterbium atom tweezer system. After moving to Innsbruck, he has mainly focused on quantum computing research based on the Rydberg-Parity architecture.
