Tunneling photons pose no challenge to Bohmian mechanics

Very recently, Sharoglazova et al. performed an experiment measuring the energy-velocity relationship and Bohmian velocity in coupled waveguides. Their data show a discrepancy between the semi-classical `speed’ $v=\sqrt{2\mathrm{\mid }\mathrm{\Delta }\mathrm{\mid }\mathrm{/}m}$ and Bohmian velocity $v_s$ for $\mathrm{\Delta }<-\mathrm{\hslash }{J}_0$, leading them to claim a challenge to Bohmian mechanics. Here, we definitively demonstrate this experiment poses no challenge to Bohmian mechanics. First, $v$ and $v_S$ represent fundamentally distinct physical quantities – comparing them is physically unjustified and cannot adjudicate between Copenhagen and Bohmian interpretations. Second, we rigorously show that both interpretations predict identical photon tunneling dynamics in coupled waveguides.
