TL;DR

This paper introduces a protocol for quantum energy teleportation in spin chains that uses ground-state entanglement and classical communication to transfer energy without violating physical laws, potentially reducing dissipation.

Contribution

It presents a novel quantum energy teleportation protocol leveraging ground-state entanglement and negative energy regions in spin chains, ensuring causality and conservation laws.

Findings

Energy can be teleported via local operations and classical communication.

The protocol does not violate causality or energy conservation.

Energy dissipation during transport is expected to be significantly reduced.

Abstract

We propose a protocol for quantum energy teleportation which transports energy in spin chains to distant sites only by local operations and classical communication. By utilizing ground-state entanglement and notion of negative energy density region, energy is teleported without breaking any physical laws including causality and local energy conservation. Because not excited physical entity but classical information is transported in the protocol, the dissipation rate of energy in transport is expected to be strongly suppressed.
