• Abstract: In our recent work (Sharoglazova et al., Nature 643, 67 (2025)), we reported the measurement of the speed of tunnelling particles using a coupled waveguide system. The measured speed was found to disagree with the standard guiding equation of Bohmian mechanics, which we regard as a challenge to that framework. In the present work, we provide a more detailed account of this issue. In particular, we argue that agreement or disagreement between standard quantum mechanics and Bohmian mechanics on quantities such as particle velocity, speed, tunnelling, and dwell times depends solely on the choice of guiding equation. If this choice is made based on observable spatio-temporal transformation behaviour of the particle density, the two theories agree on these phenomena.

  We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
