The core architecture of this experimental instrument is based on a Mach-Zehnder interferometer (MZI), and it splits a light beam into two optical paths before recombining them to produce interference fringes. By placing polarizers in each of the two split paths and a third polarizer in front of the observation screen, rotating the angles of these three polarizers elegantly demonstrates the quantum complementarity principle.

Through practical demonstration experiments that simulate fundamental quantum phenomena, this setup provides students with a concrete visualization of quantum concepts. It offers deep insights into the core properties of quantum mechanics, establishing a solid foundation for advanced studies in quantum physics courses.
