Text__nDEBwKObEd-WfYQ0GneCwQ_text=The left polarisation filter 1 can be adjusted to two fixed positions using the left switch -  at 0 degrees and 45 degrees. As soon as this filter is adjusted, the right filter 2 starts to  rotate. At the same time, the number of photon pairs arriving at each position of filter 2 is  measured by the detectors.
