Christian Kurtsiefer Group

We are an experimental group concerned with implementing quantum information building blocks with photons and atoms. We have experience in working with entangled photon pair sources and single photon detection, ranging from fundamental tests in physics to applications like quantum key distribution. Another focus is to make photons and atoms interact strongly in unconventional ways.
