Efficient Long Range Communication by Quantum Injected Optical Parametric Amplification

  • Conference paper

Abstract

Free-space optical communications over long distances are associated with severe losses while the natural limit for the energy associated to a single bit of information is just one photon. In order to enhance the transmission Efficiency we propose the use of macro qubits consisting of thousand of photons. We investigate the Fidelity of the transmission of a macro-qubit generated by quantum injected optical parametric amplification (QI-OPA) along a lossy communication channel. The realization of a QI-OPA micro-macro Teleportation protocol is considered.
