Quantum Shared Broadcasting
Abstract
Description
A generalization of quantum broadcasting protocol is presented. Here the goal is to copy an unknown input state into two subsystems which partially overlap. We show that the possibility of implementing these protocols strongly depends upon the overlap among the subsystems. Conditions for approximated shared broadcasting are analyzed.
