This glass tube was an important part of the apparatus for John Clauser’s experiment on quantum entanglement. Clauser made pioneering contributions to prove that quantum entanglement is a real phenomenon. He made the actual tube and used it to produce entangled photons in experiments in 1974 and 1976. The publication next to the test tube describes experiments and findings.
Quantum entanglement is one of the strangest predictions of quantum physics. It means that what happens to one particle in an entangled pair determines what happens with the other particle. Even if they are separated by great distances, they can influence each other. More specifically, the 1976 experiment measures correlations for the linear polarisation of photon pairs emitted in a three-level cascade in mercury.
John Clauser donated the glass tube and the publication to the Nobel Prize Museum in 2022. - Pristagare
