Michelson interferometer
The Michelson interferometer can be assembled and adjusted quickly and easily. The modular design invites you to try it out and enables an intuitive approach to interference phenomena. By adding a piezo module, quantitative measurements can also be carried out, e.g. to demonstrate quantum mechanical superpositions or to investigate tiny changes in length on the wavelength scale. Further information can be found here.
Mach-Zehnder interferometer
Some of the components from the Michelson interferometer can be reused for the Mach-Zehnder interferometer. The experiment offers a vivid opportunity to discuss interference and light splitting. Further information can be found here.
Quantum eraser
The analogy to the quantum eraser is an extension of the Mach-Zehnder interferometer. By adding polarization filters, the influence of polarization on the interference behaviour can be made visible. This provides a clear introduction to fundamental concepts of quantum mechanics. Further information can be found here.
BB84 protocol
The BB84 protocol is used to generate secure keys for cryptographic encryption. Single photons are used to transmit individual bits. In this analogy experiment, the protocol can be reproduced with many photons and its functionality can be clearly demonstrated. Further information can be found here.
Further experiments will follow.
