Abstract

A wormhole with a quantum throat on the basis of an approximate model of the spacetime foam is presented. An effective spinor field is introduced for the description of the spacetime foam. The consequences of such model of the wormhole is preventing a "naked'' singularity in the Reissner-Nordstr\"om solution with $|e|/m > 1$.
