Title   :      "A Theory of Quantum Gravity Based on Quantum Computation"

Time    :    Wednesday,  April 26, 2006 @ 4:30 p.m. - Tea @ 4:00 p.m.

Place   :    Jefferson Laboratory  * Room 356

Abstract:
This talk proposes a theory of quantum gravity based on quantum 
information processing. In this theory, distances and time intervals 
are derived from pairwise interactions between quantum degrees of 
freedom: the geometry of spacetime is a construct, derived from the 
underlying quantum information processing. The theory provides 
explicit predictions for the back-reaction of the metric to 
computational `matter', black-hole evaporation, holography, and 
quantum cosmology.
