🚨The 2025 #NobelPrize for Physics goes to John Clark, Michel Devoret & John Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantization in an electric circuit”. More details soon... ⚛️🧪
physicsworld.com/a/john-clark...
The pioneering work of Clarke, Devoret, and Martinis showed that very cold electrical circuits behave in ways that exhibit fundamental principles of quantum physics.

Both relative to V60 and French press, but before I mainly used a V60.
Not sure if there are any #coffee lovers out there among my followers? If so, this one's for you. ☕
I just got a Hario Switch after a lot of hesitation, thinking that it would not make much of a difference. After brewing a few cups with it, I am genuinely amazed by the result. Strongly recommended!
This one just dropped!
Using parameter estimation techniques to efficiently characterise Gaussian states of light.

It's a bit haunting to be alone in a room with Van Gogh...
I recommend everyone who likes art to get a carte blanche at @museeorsay.bsky.social, which gives you entry 30 minutes before the museum opens to the crowds!
Probably should have put a #quantum..
Also, shout out to my postdoc Massimo Frigerio who did an excellent job conceiving and supervising the project!
An image of a photonic circuit. Starting from vacuum states, photon creation operators and interferometers (denoted U) are applied in an alternating fashion. At the end, the top mode is measured with a photon-number resolving detector, and upon the second mode one applies a displacement operator and then postselects on a zero-photon count. The remaining modes are indicated to be in a state denoted as psi.
What happens when you put a bunch of highly talented first-year master students together with a brilliant post-doc? First, there is a lot of magic involving algebraic geometry and then you have a protocol for generating arbitrary multimode multi-photon states! 💪

📣 Le Palais de la Découverte a besoin de vous !
Musée de sciences installé à proximité des Champs-Élysées, il attire les curieux et férus de science depuis son ouverture en 1937.
Fermé depuis 2020 pour rénovation, sa réouverture est aujourd'hui menacée.
Dear friends and colleagues from the physics community, be sure not to forget that you can nominate young researchers for the early career prize of New Journal of Physics! 🏆

Hello #quantum community! Just a little heads up that there is still some time to apply !
New paper out! We resonantly couple a superconducting heavy-fluxonium qubit ⚛️ to a macroscopic membrane 🥁 oscillating at a few MHz. ~300 repeated interactions let us track its quantum motion, observe back-action & probe non-commuting operators. Diósi–Penrose next? (1/8)

The Eiffel tower is seen in the dark. The light reflects from the Seine.
Being a quantum optics group in the city of lights, we love light!
Happy international day of light, everyone!

I'm at the perfect place for a workshop on #quantum correlations 😎
Hopefully, this should make it clearer why some works get a desk rejection. However, it should also help authors avoid them by writing better 100-word justifications. These 100 words are a chance for authors to explain why submitted work is exceptional.
It's really meantime as a clarification. The way editors and editorial board members judge papers does not change, but we hope that with these reformulated criteria, it's clearer why certain are the way they are.
Our paper "Purification of Gaussian states by photon subtraction or addition" is now published in PRA! 🎉
We explore how, surprisingly, photon subtraction and addition can enhance Gaussian state purity, revealing new potential in quantum optics.

I think I completed the next level of "being french".
Don't forget to focus on these criteria in de 100-word justification. That's your chance to explain the editorial team why your work is exceptional!
📢 Service announcement for the #quantum crowd : PRX Quantum just updated its acceptance criteria.
This update is a clarification and does not change editorial practices. However, it should make it easier for you to choose what to submit to the journal.

Finally, a holiday I celebrate. Happy 4th of May from behind my mug of tea, everyone!
C'est trop bien !
Enjoy your stay!
🌟 Quantum Community, Help Needed! 🌟
My tutorial "Non-Gaussian States and Where to Find Them" needs a few updates. If you've spotted errors, please share! Let's improve it together.

One of the surprising joys of parenthood is waking up at 5.30 am and listening to the imperial march together with your baby.
The force is strong in this one...
Ah yes, a fun final observation: the optimal states at fixed energy are Fock states. This is perhaps surprisingly unexotic compared to grid states and compass states that have been proposed for this task in the past.
Once you start mixing, it's more subtle. Non-Gaussian mixtures of Gaussian states can be resourceful, but on the other hand, we even found some Wigner negative states that are worse than some Gaussian states.
It's a really fun problem, and we really learned new things about non-Gaussian states.
