About Christof Eigner

Curriculum Vitae

Since 12/2021: Head of Laboratories and Scientific Infrastructure

In the international "Photonic Quantum Systems Laboratory" (PhoQS Lab), scientists from experimental and theoretical physics, electrical engineering, computer science and mathematics work together in a building with the most modern technological infrastructure, in order to develop technology for photon-based quantum applications as well as in the theoretical and experimental concept development of a scalable quantum photonics fundamentally oriented new research approaches.

The research building provides the necessary infrastructure for this. State-of-the-art micro and nano technology processes enable the realization of miniaturized, integrated optical quantum circuits and quantum components. Manufacturing and characterization techniques are set up, further developed and made "quantum-capable"; high-quality quantum optics laboratories support the exploration of fundamental physical limits of quantum mechanics.
