Quantop Lab (image) University of Copenhagen Caption The photo shows the experimental setup for a quantum information experiment. The table is filled with optical elements such as mirrors, lenses and wave plates, which are used to guide and manipulate infrared light. Inside each of the two metal cylinders is a glass cell with caesium atoms. The two cylinders are magnetic shields which protect the atoms from magnetic fields. Shown in the upper right corner is a pair of detectors which are used to make measurements of the infrared light.
