If I have a 60-40 beam splitter, I have a semitransparent plate that will classicaly reflect 60% of the light and transmit 40%.(adsbygoogle = window.adsbygoogle || []).push({});

On quantum level, photons take both trajectories at the same time, but with different probability coefficients.

So is quantum superposition of trajectories for photons that make an object look semitransparent?

The wave gets split due to quantum tunneling, but only part of the probability amplitude of the photon leaks through the thin reflective barrier, so as a function of the thickness, we have more or less transmitted light.

Is semitransparence due to classical scattering or due to quantum superposition? Are interference patterns visible manifestations of quantum superposition?
