About me
Contact: benoit.vermersch (at) lpmmc.cnrs.fr
I am an associate professor at the University of Grenoble Alpes, member of the LPMMC. I am also researcher at the institute for quantum optics and quantum information (IQOQI), in Innsbruck.
I thank Agence Nationale de la Recherche (ANR-JCJC QRand), the Austrian Science Fundation (FWF-P32597N), and the LANEF and Nano-Science fundation, for financial support.
-Funding available for a Phd position. Contact me if you are interested.
