last week Ziao Wang defended his thesis entitled "beyond random projections : algorithms-optics synergy in complex media optical computing". Congratulations to the new doctor!

a very nice article in @lemonde.fr about the recent work of @ziaowang.bsky.social together with @lightonai.bsky.social (in french) www.lemonde.fr/sciences/art...

Un composant optique parvient à entraîner efficacement un réseau de neurones

Une nouvelle technique qui remplace les électrons par la lumière promet d’accélérer les longs calculs nécessaires à l’entraînement des modèles d’intelligence artificielle.

Come for the science, stay for the goodies ! #PICoLab

*New publication* "Streamlined optical training of large-scale modern deep learning architectures with direct feedback alignment" by our outstanding PhD student Ziao Wang, in collaboration with @lightonai.bsky.social www.pnas.org/doi/10.1073/...

Having a great time at the « image Science » GRC in Italy, we took time for a photo with current group members, alumni, and friends of @picolablkb.bsky.social !

#PICo #LKB

🚀 It’s a new era for our team at Kastler-Brossel! Goodbye "Comedia", hello PICo Lab (Photonics, Information & Complexity). A new name to reflect the evolution of our research at the intersection of optics and computer science. 🚀

#NewPreprint Check out this new paper in collaboration with Tsinghua University and spearheaded by current and former team member Ziao Wang and Hao Wang. "Training deep physical neural networks with local physical information bottleneck" arxiv.org/abs/2602.09569

And 🥁 the final program of the *"Image Science" Gordon Research Conference*, to take place in Italy April 26-May 1st, is out! Please take some time to check the program, apply, *share* with your colleagues. www.grc.org/image-scienc... (1/N)

A merry Christmas from the COMEDIA team at LKB !

I was deeply honored to receive yesterday the Cecile DeWitt Morette Prize / Ecole des Houches / CFM foundation prize from the french @academiesciences.bsky.social, crowning a lot of hard work, creativity and fun with my team @comedialkb.bsky.social. Thank you!

Check out this upcoming symposium organized by hugo Defienne's team and us. Register here : quantumcomplex.sciencesconf.org

#NewPreprint #Quantum "Harnessing Optical Disorder for Bell Inequalities violation" a joint work with Hugo Defienne's team. arxiv.org/abs/2509.21052 In short : a speckle essentially has a random polarization state at any position, we exploit this to show we can violate a BI.

This is the end of a short visit to ETH Zurich, I was very intimidated to visit the math department (as an experimentalist) but it turned out great, thanks to my host Habib Ammari. Also great to (re)connect to colleagues in Physics, Mechanics & engineering, and enjoy a nice Picasso exhibition.🇨🇭🧀🍫

#NewPaper on the blend of computational microscopy with chemical imaging: enabling high-speed quantitative CARS imaging via a new compressive Raman framework. Kudos @spzhao0724.bsky.social A collaboration between @lkblab.bsky.social and @ukmlv.bsky.social from Washington Uni St.Louis rdcu.be/eCjLz

Always a pleasure to have the visit of our alumni! Today Michael Mounaix from U Queensland gave us a seminar on his impressive recent work on arbitrary light shaping using an MPLC, including a demonstration using the team chicken !

If you’re in CLEO Munich don’t miss the talk of Malo Joly today at 11 on Quantum Extreme Learning Machines !

Congrats to our newly minted PhD, Lea Chibani, who successsfully defended today !

Finally out ! journals.aps.org/prresearch/a... "Classification of quantum states of light using random measurements through a multimode fiber" after several years, the last work of the PhD of Saroch Leedumrongwatthanakun, collaboration with Mauro Paternostro's group, is out in Phys. Rev. Research.

We have multiple postdoc openings in *optical computing* 🔦+🤖, *computational microscopy* 🔬+🧠, and *nanophotonics*💡+⚛️. Don't hesitate to get in touch / spread the word!
