<b>Date:</b> 16/1/14<br>
<b>Time:</b> 11.00am<br>
<b>Location:</b> JA 5.05<br>
<b>Abstract:</b> 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.<br>
