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.

建立了量子能量隐形传态（QET）的最小模型，并发现了能量纠缠关系。在量子电磁场系统中，证明了通过QET协议获得更多的基态涨落信息可以传送更多的能量。在一般的自旋链系统中，得到了能量纠缠关系，并证明了基态纠缠熵是与传送能量的平方成正比的量的上界。提出了一种利用量子霍尔边电流进行QET实验的可行方案。结果表明，即使在有限温度条件下，QET仍然有效。
