- ridiculously nice panoramic ride through the alps on my way back from Innsbruck. my moving office 🚂 >> your static office 🖥️
- On my way to Innsbruck by train through Zurich - since there is no direct flight, train is (i) cheaper (~150€) (ii) faster (8.5h) and (iii) infinitely more comfortable. Looking forward to giving a colloquium and visiting old friends! 🛤️ 🗻
- I've got some questions from my 11yo about black holes, which led to a long discussion and some nice youtube videos binge watching together. I must say Astronomy is a nice way to captivate kids with physics....
- Completely packed amphitheater for the first lecture of Pascale Sennelart at @college-de-france.fr for her annual chair on quantum technologies !
- so I have this ominous event in my calendar that says "deadline" tomorrow at 9am but I have no clue what this is... 🤷♂️#AcademicChatter
- Sleep and some sleuthing has helped... this is actually a deadline FOR MY STUDENTS TO SEND ME SOMETHING. 😅
- 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)
- Check out our amazing speakers across imaging modalities, from Optics to X-ray and acoustics, from consumer device to astronomy and medecine, from hardware to AI. (2/N)
- Gordon Research Science are unique events : they provide an immersive single-track environment. It is the ultimate career-changing platform for young scientists to showcase their work, build a lifelong network, and shape the future of imaging alongside global leaders. (3/N)
- Come for the single-track program, stay for the deep conversations and the unpublished cutting-edge research. (4/4)
- and it happened : I just came to realize I didn't fly for work in 2025 (I did fly a bit for personal reasons). It wasn't an objective per se, but just being (a bit) picky, and looking for train alternatives when possible did the trick. and I did go to IT, NL, CH, UK, GE, CZ.
- oups - I just realized I forgot a flight to Sicily :-( so much for 2025 😅 still quite a reduction ....
- Reposted by Sylvain GiganA merry Christmas from the COMEDIA team at LKB !
- Advanced Imaging, the journal that I have the pleasure to serve as (co)Editor-in-chief, has just published its first "interview" article, with *David Brady*, inventor of the Gigapixel camera. Read it here ! (open access) www.researching.cn/articles/OJe...
- 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!
- It was nice visiting Willem Vos's COPS group last week ! thanks for the warm welcome and great science discussion !
- Reposted by Sylvain Gigan📣 Venez visiter le Laboratoire Kastler Brossel, un des acteurs majeurs de la physique quantique, sur le campus Pierre et Marie Curie ! 👉 RDV les 11 et 12 octobre à la Fête de la Science de Sorbonne Université : swll.to/nhwZkg6 #FDS2025
- Back home after a great 3-day trip to the NL, for the NNV-AMO meeting, and visiting COPS in Twente and Allard Mosk's group at U. Utrecht. No cheese this time, but I couldn't come back with a collection of great PhD thesis :-). (why do we do A4 format in France? this is soooo much better!)
- I couldn't come back---without--- a collection of PhD thesis ! #Typo #doublenegation
- Reposted by Sylvain GiganCheck out this upcoming symposium organized by hugo Defienne's team and us. Register here : quantumcomplex.sciencesconf.org
- A strong quality for a good researcher is the ability to sometimes ignore small details, and sometimes delves into them with the greatest care, and more importantly to being able to switch wisely between the two modes.
- it is easy to get lost in details and lose the big picture (and never get anything done), and conversely it is easy to have a grand idea which is totally infeasible because details don't add up.
- Getting lost in small details is typical for junior researchers, and as a PI, it is important to teach them to keep the big picture in mind. But it is easy (and mortal) as PI to lose track of the importance of small details and I am usually grateful to my team members to keep me grounded.
- une fois de plus, le Gorafi tue le game.
- Panini annonce la sortie de l'album des Premiers ministres sous Emmanuel Macron legorafi.fr/2025/10/08/panini-a…
- very honored to give the opening lecture tomorrow at the NNV AMO meeting in Egmond aan Zee (NL). Very curious to see what happen if -probably- the Physics prize is announced during my lecture (probably nobody will pay attention to the second half of my lecture).
- a national treasure of french science!
- 🔬For 22 years, we have been organizing #Mifobio "Functional Microscopy for Biology" the @cnrs.fr thematic school. 🎓 Courses, Seminars, Round Tables, Workshops. The overall theme concerns #biological_imaging in its most interdisciplinary aspects. 👉 Program: imabio-cnrs.fr #GDRImaBio #Mifobio2025
- Very happy about this one, a great work by Baptiste Courme, and an old dream coming true : we can demonstrate a violation a Bell inequality just by sampling random polarization states from speckle field.
- #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.
- 🚨Registrations are open for the upcoming "Image Science" Gordon research conference , to take place in Italy, April 26-May 1, 2026. Check out the amazing program, tell your friends and share, APPLY! 🚨 www.grc.org/image-scienc...
- 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.🇨🇭🧀🍫
- Well hidden in a small corner of the main building of ETH Zurich, they have made a mini museum for Einstein in his former locker 😍
