Welcome to our group website!
Open positions: We currently offer several Bachelor's and Master's thesis projects. If you are interested, drop us a line and come along for a lab tour!
News:November 18, 2024 Felix's latest Optics Express paper was highlighted as an Editors Pick - Sven: "Super well deserved!" :)
November 11, 2024 And there were already 10 of them... We welcome Theresa to our group as a new Bachelor student!
November 06, 2024 A two-hour lecture by Nobel Prize winner Alain Aspect at the French Embassy - felt much shorter - what an amusing speaker! And a glass or two of red wine afterwards to get into conversation...
November 04, 2024 Felix has published his paper on "Noise analysis of a quasi-phase-matched quantum frequency converter and higher-order counter-propagating SPDC". Congratulations!
October 31, 2024 We spent a fantastic 3 days with the 'Sensing with Quantum Light' community on board the beautiful MS Crown on the Danube during our self-organized SQL24. From the first talk by Bob Boyd to the last evening in the hot tub on deck, it was perfect all round!
October 21, 2024 We are happy to welcome Anna as a new PhD student!
