This apparatus was used to produce entangled photons in Anton Zeilinger’s experiment on quantum entanglement. A crystal for down conversion is in the round hole. This was used to produce photon pairs from a beam of photons. The larger metal tube is a Pockels cell used to change the polarisation of the light passing through the tube. It was used in experiments in the late 1990s. The smaller tube is a newer type of Pockels cell.
More specifically, Zeilinger’s experiment was about how unknown quantum states can be transferred from one particle to another: quantum teleportation.
Anton Zeilinger donated the apparatus to the Nobel Prize Museum in 2022. - Location
