Visualisation 1.mov

A video demonstration of our automated tomography system in action is provided. Both the projected states, as acquired by the CCD camera, and the angular positions of each roto-flip stage are highlighted. In the video, the system can be seen iterating over the 36 angular positions of the polarisation optics (two pairs of quarter- and half-wave plates), which are required to identify an unknown input state. We hope that this video demonstration may facilitate the assimilation of the concepts covered in this tutorial and help the reader appreciate what, from a practical point of view, a state tomography measurement involves.
