Wave–particle duality revisited

The notion of wave–particle duality remains one of the most debated subjects in the history of quantum physics. The most famous debate on the subject occurred between Bohr and Einstein. In this work, we revisit the wave–particle duality in the Bohr–Einstein debate from the viewpoint of the recently established duality-entanglement relation. We show that the duality-entanglement relation can provide a valuable framework for quantitative analysis of the Einstein's gedanken double-slit experiment and clarify some of its fundamental aspects.

This project revisits wave-particle duality by simulating single-photon interference in a Mach–Zehnder interferometer using Python. Results from this research show that interference emerges not because photons are both waves and particles, but because their probability amplitudes add coherently in superposition, which simplifies the interpretation of complementarity and connects directly to modern applications of quantum photonics in communication and quantum information processing.
