Quantum control of an ultracold quantum gas
This thesis is devoted to the study of quantum control of an ultracold atomic ensemble of $^{87}$Rb. Stroboscopic probing is used to achieve real-time tracking of the collective spin magnitude and orientation via non-destructive Faraday probing.

| Summary: | This thesis is devoted to the study of quantum control of an ultracold atomic ensemble of $^{87}$Rb. Stroboscopic probing is used to achieve real-time tracking of the collective spin magnitude and orientation via non-destructive Faraday probing. By means of an RF feedback scheme we achieve a reduction in angular dispersion of the precessing spin down to a circular standard deviation \textit{circ std}$(\phi)$=\SI{0.11(3)}{\radian}. |
