1/ Here is a proposalΒ of how to distinguish between different, supposedly "equivalent," #orthogonal mixtures of photons. In this case, it is RΒ + L mix of circular, to be distinguished from mixtures of linear #polarization.

I am leaving aside right here whether it could lead to #FTL communication (#SuperluminalSignalling), and focusing on the bare being able to make the distinction. Impractical - but of major theoretical importance.
#ProperMixtures #MeasurementProblem
We use a compound detector D for this purpose. Its first element is a quarter-wave plate with horizontal fast axis, that is rotationally free within a small angle (to allow measurement of changes in #angularmomentum of roughly a few hundred Δ§, which is still very tiny.)
