Towards simultaneous observation of path and interference of a single photon in a modified Mach–Zehnder interferometer

Fenghua Qi, Zhiyuan Wang, Weiwang Xu +2 more

Classical wisdom of wave–particle duality regulates that a quantum object shows either the particle or wave nature but never both. Consequently, it would be impossible to observe simultaneously the complete wave and particle nature of the quantum object. Mathematically the principle requests that the interference visibility V and which-path distinguishability D satisfy an orthodox limit of V 2 + D 2 ≤ 1 . The present work reports a new wave–particle duality test experiment using single photons in a modified Mach–Zehnder interferometer to demonstrate the possibility of breaking the limit. The key element of the interferometer is a weakly scattering total internal reflection prism surface, which exhibits a pronounced single-photon interference with a visibility of up to 0.97 and simultaneously provides a path distinguishability of 0.83. Apparently, the result of V 2 + D 2 ≈ 1.63 exceeds the orthodox limit set by the classical principle of wave–particle duality for single photons. We expect that more delicate experiments in the future should be able to demonstrate the ultimate limit of V 2 + D 2 ≈ 2 and shed new light on the foundations of contemporary quantum mechanics.

The Null-Interval Bridge: A Relativistic Foundation for Wave-Particle Duality

Urs Stettler, Gemini-Flash

Universal quantum paradoxes, specifically wave-particle duality and the double-slit experiment, are traditionally viewed through the lens of a mass-bound observer. This paper proposes a resolution based on the limit of Special Relativity: as a particle's velocity v approaches c, both observed space (L) and proper time (τ) contract toward zero. At the limit of c (the photon),L = 0 and τ = 0. We argue that the "wave" observed in quantum mechanics is the relativistic artifact of a zero-length spacetime bridge being projected into a four-dimensional coordinate system. Under this model, a photon does not "travel"through slits; it exists simultaneously at all points along its light-like worldline, interacting with the entire geometry of the experiment as a single, static event.
