LKB - Atom chips group

Atom Chips Group

We study fundamental many-body quantum physics and its applications, especially in quantum metrology and quantum information. To gain access to new physical situations, we also develop novel technological tools, such as atom chips and fiber Fabry-Pérot microcavities.

Our collaboration with Olivier Arcizet’s group at Institut Neel has allowed mapping of the microscopic standing-wave field in a fiber Fabry-Perot microcavity with a nanowire probe that is sensitive to the field of a single photon. This work just appeared in Physical Review X on 8 April 2021. The CNRS published a News item about this work (in French).

The atomchips group continues working during these exceptional circumstances, but the office looks a bit different these days. We are grateful we can meet virtually and continue to discuss on our latest results!

We are looking for a postdoc for our strontium cavity QED project!
