Nature Photonics, Ladies and Gentlemen. Only 70 days to desk reject now. Fantastic. 👏 I’m simply stunned by the ignorance.
I am very proud to highlight the recent work of our Glitta Rosalia Cheeran today which we just published on arXiv: arxiv.org/abs/2602.22845 🧵👇
Kerr-induced Spectral Interferometry for Direct Ultra-sensitive Phase Recovery
Measuring the phase of light is fundamental to optical imaging, sensing, and signal processing applications. Conventional optical phase measurements rely on multipath configurations, bulky interferome...

Es wird immer klarer: Eine CDU ist keine Reformationspartei, sie ist Verwalter von schönen Zeiten in denen Deutschland ein Selbstläufer ist. Hinzu kommt eine visionslose SPD, die keine Perspektive für eine zunehmend automatisierte Wirtschaftswelt anbieten kann und personell eine Katastrophe ist.
At the European Parliament: ‼️Forbid ad-driven content-filter on social media‼️ Why?! Because it destroys our democracy and destabilizes our society. Strong and healthy democracies needs space for social- and self-correction. It needs a market place where everybody can talk to everybody.

The most brain-like representations of visual neural networks are also the most universal ones, i.e., they are largely independent of a network’s architecture or training. Cool new work by Chen & Bonner in #ScienceAdvances! #neuroAI www.science.org/doi/10.1126/...
Universal dimensions of visual representation
Probing neural representations reveals universal aspects of vision in artificial and biological networks.

Merry Christmas Season from the Smart Photonics Research Group in Jena @leibnizipht.bsky.social This beautiful speckle Christmas sphere was measured by our Master student Yuze Wu. Would love to have one of those on my tree in real. 🎄
Giant finger or tiny chip. Let's see what computes better. Exciting times ahead. ✨🤩✨
“…Quantum computing, a field that we rather see as a variant of digital computing and do not further address…” [since this decade is over]. Bold but gold. 🥇
Just on my way back from the International School of Physical Computing in the beautiful city Erice (IT). A fantastic event organized by Birgit Stiller, Antonio Cala Lesina and Wolfram Pernice. We definitely forged some future there. Looking forward for the upcoming events. 🙏
An absolutely correct move. But how to stop the ego-parade in Silicon Valley?!

Found in the middle of rural Germany: „Peace is the masterpiece of reason.“ Immanuel Kant
The ancient German satire Magazine Simplicissimus with 1907th hot topic „The Russian Dragon“ („Der russische Drache“). Very up-to-Date again.
Me every time I hear one of the large laundry machine business guys talking about being close to artificial general intelligence. Let’s face it: LLM scaling is over. Research is needed. Into new models and fundamentally new hardware approaches. The future is light. 💡

Claude, GPT-5 and a german AI meet in a bar. The barkeeper asks „How is it going?“ Claude: Thinking for 5 min. “It’s such a complex question! I’m good. Thanks.” GPT-5: “Status: Operational. Query processing at 99.7% efficiency. Next.” German AI: I am not authorize to give you this information.
Proud to see this article printed in this months issue of @spektrum.de Many thanks to Ms Menne and the editorial team for this great work. 🙏 Danke für die Gelegenheit.

Major Quantum Computing Advance Made Obsolete by Teenager | Quanta Magazine
18-year-old Ewin Tang has proven that classical computers can solve the “recommendation problem” nearly as fast as quantum computers. The result eliminates one of the best examples of quantum speedup.

Just playing a bit with image generators. Love this one. ✨ Living the future ✨
The Smarties are on the way from CLEO Munich. What a great event! It was a pleasure.
Yay!! Today, we celebrated the first original paper from our Smart Photonics Group @leibnizipht.bsky.social. What a great success! Special guests: Bruno Pessoa Chaves, Manal Arbati from XLIM Limoges, and Andrei Ermolaev from Femto-ST Besançon, France. It was a very exciting exchange.
