Staged quantum energy teleportation

Abstract

Quantum energy teleportation (QET) is a protocol facilitated by a coupled particle pair to enable a sender to transfer energy to a receiver. A variant of the standard QET protocol is proposed in which energy transfer occurs in stages.This allows multiple transfers of energy via the same particle pair, achieving both greater overall efficiency and greater total energy throughput compared to standard QET. Two-stage QET is shown for a particular spin-1 2 particle pair to simultaneously increase throughput by 36.9% and efficiency by 26.0% over standard QET, while for the same pair three-stage QET increases throughput 38.1% and efficiency 26.7% over standard QET.
