SU(2) structure of entangled states

Not Accessible

Your library or personal account may give you access

Abstract

It is shown that the entangled states of a two- or multi-component system form a representation of the SU(2) phase states. The use of the dualism of base and entangled states is proposed for the quantum information transmission secured from eavesdropping.
