Observing relativistic trajectories of single photons IJQF Weekly Papers • quant-ph updates on arXiv.org / 20h arXiv:2608.26778v1 Announce Type: new Abstract: While the standard interpretation of quantum mechanics does not assign definite trajectories to particles, the Bohmian interpretation does. Only recently has an operational method for reconciling Bohmian mechanics with relativity been proposed. Here, we experimentally reconstruct relativistic Bohmian trajectories of a… Read more →
