The Mach-Zehnder interferometer is a Book I topic in the Quantum Collection. It is an interferometer in which a beam is split into two paths and later recombined so that phase differences appear as changes in output intensity or detection probabilities. In quantum mechanics the device can be used with single photons, atoms, or other particles, making it a clear example of path superposition and interference. It connects beam splitters, phase shifts, which-path information, complementarity, and quantum measurement. Variants are used in precision metrology, quantum optics, delayed-choice experiments, and tests of wave-particle duality.
