  The paper is a Chapter of a book. In it an exhaustive review of the proposals
to send faster than light signals resorting to quantum nonlocality and the
reduction process is presented, together with a critical analysis and rebuttal
of all proposals. The most interesting part of the Chapter is the one in which
the problem of quantum cloning is discussed. Actually, a proposal of
superluminal signaling based on an hypothetical cloning machine has been
presented by N. Herbert. The proposal does not work just because of the
assumption that one can clone nonorthogonal states. The fact that such a
machine is incompatible with quantum theory (i.e., the so-called No-Cloning
Theorem) has been proved, for the first time, by the author of the present
chapter in his referee's report to Herbert's paper. In the final part of the
paper some recent (different but similarly not correct) proposals are analyzed
and the reasons for which they are basically wrong are presented.
