| Research Abstract |
A minimal model of quantum energy teleportation (QET) was constructed and energy-entanglement relations are discovered. In the quantum electromagnetic field system, it was proven that getting more information about the ground-state fluctuation leads to teleporting more energy by QET protocols. In general spin-chain systems, the energy-entanglement relations were obtained and show that the ground-state entanglement entropy is a upper bound of a quantity proportional to the square of the teleported energy. A realistic proposal for QET experiment was proposed using quantum Hall edge current. It was also verified that even for the systems in finite temperature QET remains effective.
