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!

Optimal Moment-based Characterization of a Gaussian State Fast and precise characterization of Gaussian states is crucial for their effective use in quantum technologies. In this work, we apply a multi-parameter moment-based estimation method that enables ra...

Our theoretician Ilya Karuseichyk and experimentalist Niels Tripier-Mondancin put their heads together and developed a new, and provably optimal, method to characterise Gaussian states! 😎

Niels reads a piece of paper with pictures on the background. He is wearing a ribbon that says "Dr Niels"

People applauding Niels, who shows his strength. In the foreground, we see the food for the reception waiting.

They grow up so fast... After a valiant defence of his thesis, our very own Niels Tripier-Mondancin is henceforth Dr. Niels! 🥳

Relating the Hall conductivity to the many-body Chern number using Fermi's Golden rule and Kramers-Kronig relations - Laboratoire Kastler Brossel The quantum Hall effect is a remarkable phenomenon, initially discovered in 2D electronic systems subjected to strong magnetic fields.

💡 Discover the work of Nathan Goldman and Tomoki Ozawa on their simple derivation of the relationship between Hall conductivity and the many-body Chern number!

Hello world 👋

To start our Bluesky adventure (and the weekend), we have a nice announcement 📢

Our postdoc (we prefer to call him our quantum engineer 😎) David Fainsin won a prize at the Valorisation Awareness Day of QuanTiP!

Congratulations David 🥳 🍾
