Abstract

An unsolved problem in relativistic quantum information
research is how to model efficient, directional quantum communication between
localised parties in a fully quantum field theoretical framework. We propose a
tractable approach to this problem based on calculating expectation values of
localized field observables in the Heisenberg Picture. We illustrate our
approach by analysing, and obtaining approximate analytical solutions to, the
problem of communicating quantum states between an inertial sender, Alice and
an accelerated homodyne receiver, Rob. We discuss the effect on quantum
protocols carried out over such a communication channel.
