Extended version 1.2 Quantum Energy Teleportation: An Introductory Review

The development of techniques for manipulation of quantum in-formation has opened the door to a variety of protocols for accom-plishing unprecedented tasks. In particular, a new protocol of quan-tum teleportation was proposed in 2008 to achieve e¤ective energy transportation simply via local operations and classical communica-tion without breaking any known physical laws. This is achieved by extracting zero-point energy of entangled many-body systems by local operations dependent on information obtained by a distant mea-surement. The concept is reviewed from an introductory viewpoint herein.
