  We propose a bimetric space-time consisting of two vierbein bundles, in which
a superluminal S-field mediates a causal exchange of quantum information
associated with quantum entanglement. The resulting theory leaves the usual
quantum field interactions, as well as the speed of light unchanged, but
introduces quantum information effects related to the S-field vierbein bundle.
We show that such S-field interactions with the Dirac field, affect its spin
density, as we would expect for a field that would impart entanglement related
information.
