The development of techniques for manipulation of quantum information has opened the door to a variety of protocols for accomplishing unprecedented tasks. In particular, a new protocol of quantum teleportation was proposed in 2008 to achieve effective energy transportation simply via local operations and classical communication 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 measurement. The concept is reviewed from an introductory viewpoint herein.

Nonlinear particle detectors across the Rindler firewall
Quadratic-momentum and energy-density Unruh-DeWitt detectors yield ill-defined distributional products and δ(0) divergences across a Rindler firewall, unlike finite derivative coupling.

Harvesting entanglement from the Lorentz-violating quantum field vacuum in a dipolar Bose-Einstein condensate
Dipolar-BEC density fluctuations serve as a Lorentz-violating vacuum; two impurity detectors can harvest entanglement from it, with the optimal detector gap and switching-width behavior differing from the Lorentz-inva...

Does Entanglement Correlation in Ground State Guarantee Quantum Energy Teleportation?
For a parity measurement on the toric code ground state, no Bob-side local unitary can extract energy, so this entangled state does not support QET for that protocol.
