The metal box is an optical switch and was the crucial component in Alain Aspect’s experiment on the phenomenon of quantum entanglement in the early 1980s. The experiment was to create entangled photons. When Aspect was planning to conduct the experiment, he could not find a company that could deliver an optical switch with the right specifications. So, he was forced to build this switch. His experiment confirmed that quantum entanglement is a real phenomenon.
Alain Aspect donated the optical switch to the Nobel Prize Museum in 2022. - Location
