Conformal Symmetry and quantum localization in space-time


Using conformal symmetries, Einstein procedure for localization in space-time may be implemented in the framework of quantum field theory. This allows one to represent positions in space-time as quantum observables and to obtain quantum generalizations of the classical relativistic transformations.
