What is a photon?

5. August 2021 | by Prof. Gerhard Rempe

On the occasion of the digital anniversary event "10 years PhotonLab", the student laboratory at the Max Planck Institute of Quantum Optics (MPQ) in Garching, quantum physicist Prof. Gerhard Rempe, director at the MPQ and physics professor at the Technical University of Munich, asked the question in his popular science lecture: "What is a photon?" 

A good 35 minutes later, after an equally informative as entertaining science discourse followed by an outlook on future possibilities in the field of quantum computing, communication and crytography, he arrives at an answer that is both interesting and perhaps surprisingly simple! The whole talk from July 23, 2021 can now be streamed here on photonworld.

The talk is in German language. However, the accompanying text and images are in English.
