We implemented a student lab and demonstration experiment, which can be used to demonstrate the quantum fluctuations of the electromagnetic field (light). The foundation of this portable experiment is described in the reference below [1].

On a regular basis, the setup is used in the advanced lab courses within the Master's courses and also within the lectures on quantum optics and photonics.
