MINES ParisTech publishes in Nature

Pierre Rouchon, a research academic, and Hadis Amini, a Ph.D. student at MINES ParisTech, contributes an article published in Nature on 1st september 2011!

MINES ParisTech has been actively involved in an experiment on the stabilization of a quantum state conducted by a team from the Kastler Brossel (CNRS/ENS/Collège de France/UPMC-Université Pierre et Marie Curie). The researchers succeeded in maintaining a constant number of photons in a high quality micro-wave cavity. They have described the results of their study in the online edition of Nature published on 1st september 2011.

The experiment is the result of collaboration between the Kastler Brossel Laboratory (LKB) at the Ecole Normale Supérieure of the street of Ulm, the Automatic Control and Systems Centre (MINES ParisTech - CAS) and the Sisyphe proejct team at Inria. Thanks to Hadis Amini (Ph.D. student), and Pierre Rouchon (Professor), MINES ParisTech has contributed to the control algorithm with filter which estimates the quantum state of the system and with the stabilizing feedback based on a Lyapunov approach. 

The article is entitled "Real-time quantum feedback prepares and stabilizes photon number states". The authors include Clément Sayrin, Igor Dotsenko, Xingxing Zhou, Bruno Peaudecerf, Théo Rybarczyk, Sébastien Gleyzes, Pierre Rouchon, Mazyar Mirrahimi, Hadis Amini, Michel Brune, Jean-Michel Raimond and Serge Haroche. 



About MINES ParisTech

As the leading academic institution in France by virtue of its volume of contractual research, MINES ParisTech contributed to the competitiveness of companies. Via its 5 research departments, the School meets challenges in three main socio-economic sectors: future energy sources and the environment, the harnessing and exploitation of resources and new materials, and innovation methodologies and processes. In anticipation of the needs of industrial players, it has pioneered the creation of company chairs on emerging themes. MINES ParisTech is a founding member of ParisTech, which has brought together 12 of the leading executive engineering and management schools in Paris. Since its creation in 1783, MINES ParisTech has trained high-level engineers capable of solving complex problems in a wide variety of fields.
