[Cnqo] Talk tomorrow 11.00am

[Stefan Kuhr]

Dear all,



I would like to invite everyone to join another seminar tomorrow:



Speaker: Dr Bruno Peaudecerf, Ecole Normale Supérieure, Paris

Title: Feedback loops applied to the measurement and control of light in a cavity
Date: 16/1/14
Time: 11.00am
Location: JA 5.05
Abstract:  I will present the real-time control experiments that were performed in the cavity QED group of  Serge Haroche at LKB (Paris). In our experiments, a stream of Rydberg atoms interacting dispersively with the microwave field in a cavity perform a quantum non-demolition measurement of the photon number by a succession of weak measurements. Taking into account all measurement outcomes, the measurement back-action and all experimental imperfections, a control computer can estimate the state of the field in real time. This allows for the implementation of feedback loops in the experiment, aiming at improving the measurement efficiency, or controlling the quantum state of light.



Best regards,



Stefan
