Preparation of ultracold atom clouds at the shot noise level

We prepare number stabilized ultracold clouds through the real-time analysis of non-destructive images and the application of feedback. In our experiments, the atom number \({N\sim10^6}\) is determined by high precision Faraday imaging with uncertainty \(\Delta_N\) below the shot noise level, i.e.,...
