can coherence be restored (after de-coherence)?
let's look at single particle (interference) in a double slit experiment:
when we try to gain which way ...
the ordering of the phase angles between the components of a photon in a quantum superposition is disturbed/changed (?)
can we restore the coherence back?
is this question conceptually similar to - can entropy be restored?
on a separate note:
We can introduce a phase difference, between say the two paths of a photon, say via placing a half/fully silvered mirror on one of the paths. We can zero out the phase difference via another half/fully silvered mirror on the other path.
Thus we are able to introduce a phase difference and again reduce the phase difference back to zero as long as there is no measurement.
