There is no way to send useful signals faster than light even in
quantum theory.  Some of the abstract entities in the theory can
"propagate" faster than light but that is not the same thing as
practical signaling.  Also note that classical quantum theory is
non-relativistic and a more careful theory must be used when
investigating such matters.  My understanding of the Bell inequalities
is that they demonstrate the incompatibility of simplistic
superposition (linear) quantum theory and relativity.

In the above I have not bothered to take into account the
demonstrable isomorphism between subluminal and superluminal speeds
explained some time back in this mailing list.
