Single elementary quanta exist as waves and/or particles. The outcome
depends wholy on the measurement. This is not a consequence of
any interaction of large numbers of these entities (or even two).
A classic example is the two slit experiment.
However i do not see what this has to do with logic... It only
implies that our approximation of the world as being composed
of discrete things like particles and non-localized things like
waves is, at best, incomplete.
