  This paper shall define and discuss two types of quantum process -
Disentangling and Entangling. The first type will be shown to contradict
Unitarity and is therefore ruled out as a possible signalling process within
standard linear Quantum Mechanics. The paper will argue that the second type -
the entangling process - is both allowed by the principles of Quantum
Mechanics, and can transmit superluminal signals. A proposal will be made for
addressing the objection to superluminal signalling by the Special Theory of
Relativity.
