People standing at MPL's Science Tent in Erlangen, getting to know more about our research.

A scientist explains an experiment which can be seen on a monitor to a visitor.

MPL director Prof. Florian Marquardt presents his research in quantum science in a small talk.

People are standing at the tent of our partner Deutsches Museum Nürnberg and getting explained the experiments there.

Experiments, quantum physics and curious minds: Together with the #DeutschesMuseumNürnberg, we celebrated #DayOfLight and #IYQ2025.

A big thank you goes to all those who visited us. Your curiosity & enthusiasm made the day special!

Just back from a fantastic trip to the B-PHOT Student Chapter at @vubrussel.bsky.social, #IDL2025 Light Night & the @carlahub.bsky.social conference. Incredible enthusiasm and energy! Thanks to @astchalyan.bsky.social , @tatev.bsky.social & all Chapter members! What am I measuring in the photo?

In the picture there is a colorful lightbulb, held by a hand, in front of a black background.

💡 Lights on! One month to go until ›International Day of Light‹

Join us on May 16 for hands-on experiments, short talks & science at its brightest – in Erlangen’s city center and at #MPL.
