  The relation between quantum theory and special relativity is peculiar. On
the one hand it is close and essential. Steven Weinberg [1], for example, takes
the position that the standard model is an inevitable consequence of the
marriage of the two theories. On the other, the action at a distance implied by
the famous paper by Einstein, Podolsky, and Rosen [2] is certainly contrary to
the implications of special relativity in spite of the fact that it does not
allow transmission of information. The setting of quantum theory is a Hilbert
spaceH and a path inH whose development in time is governed by a one parameter
group of unitary transformations while the setting for special relativity can
be thought of as Minkowski space with the time development not absolute, but
dependent on the inertial system of the observer. The problem is to show how
these two very different viewpoints can be reconciled in a way that includes an
explanation of the "action at a distance" conundrum.
