On the paradoxical aspects of new quantum experiments

Vaidman, Lev (1994) On the paradoxical aspects of new quantum experiments.

Abstract

Two recently proposed quantum experiments are analyzed. The first
allows to find an object without ``touching'' it. The second allows to
teleport quantum states, transmitting a very small amount of
information. It is shown that in the standard approach these
experiments are in conflict with the intuitive notions of causality
and locality. It is argued that the situation is less paradoxical in
the framework of the many-worlds interpretation of quantum theory.
