Query: Two faced Janus of quantum nonlocality   This paper is a new step towards getting rid of nonlocality from quantum
physics. This is an attempt to structure the nonlocality mess. "Quantum
nonlocality" is Janus faced. One its face is projection (Einstein-L\"uders)
nonlocality and another Bell nonlocality. The first one is genuine quantum
nonlocality, the second one is subquantum nonlocality. Recently it was shown
that Bell "nonlocality" is a simple consequence of the complementarity
principle. We now show that projection nonlocality has no connection with
physical space. Projection state update is generalization of the well known
operation of probability update used in classical inference. We elevate the
role of interpretations of a quantum state. By using the individual (physical)
interpretation, one can really get the illusion of a spooky action at a
distance resulting from L\"uders' state update. The statistical interpretation
combined with treating the quantum formalism as machinery for update of
probability is known as the V\"axj\"o interpretation. Here one follows the
standard scheme of probability update adjusted to the quantum calculus of
probability. The latter is based on operating with states represented by
vectors (or density operators). We present in parallel classical and quantum
probability updates. From this presentation, it is clear that both classical
and quantum "faster-than-light change of statistical correlation" take place in
mental and not physical space.
