Stephan Ritter obtained his PhD degree in physics from ETH Zurich. He then joined the Max-Planck-Institute of Quantum Optics in Garching, Germany, to develop single atoms in high-finesse optical resonators into universal nodes of an elementary quantum network.
In 2017, Stephan joined TOPTICA Photonics, where he is currently leading the Quantum Technology Solutions team. Stephan is a member of the Executive Team of the European Quantum Internet Alliance (QIA) and of the Advisory Board of the German joint quantum-repeater-link project QR.X.
