- Abstract: Bhati and Arvind [Phys. Lett. A, 127955 (2022)] recently argued that in a
specially designed experiment the timing of photon detection events
demonstrates photon presence at a location at which they are not present
according to the weak value approach. The alleged contradiction is resolved by
a subtle interference effect resulting in anomalous sensitivity of the signal
imprinted on the postselected photons for the interaction at this location,
similarly to the case of a nested Mach-Zehnder interferometer with a Dove prism
[Quant. Stud.: Mat. Found. 2, 255 (2015)]. We perform an in depth analysis of
the characterization of the presence of a pre- and postselected particle at a
particular location based on information imprinted on the particle itself. The
theoretical results are tested by a computer simulation of the proposed
experiment.

The behavior of quantum entanglement during scattering is identical to the behavior of initially classically correlated photons up to a constant factor equal to two.
Our dedicated experiment with photons confirms these results and explains the "Puzzle of Decoherence" observed recently.

We show that our scheme can generate a high-quality image of an object even against noise levels up to 250 times the actual signal of interest.

Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
