摘要：

We propose of protocol of quantum energy teleportation that transports energy in spin chains to distant sites by only local operations and classical communication. The protocol uses ground state entanglement and localized negative-energy excitation, and the energy is teleported without breaking any physical laws including causality and local energy conservation.
