近年来，量子纠缠态在量子隐形传态、量子计算等量子信息理论领域中发挥着重要作用。量子纠缠态的研究已经进行了使用几种措施。在这封信中，我们将采用量子互熵的方法来测量Jaynes-Cummings模型时间发展中的纠缠度。
Recently, it has been become known that a quantum entangled state plays an important role in fields of quantum information theory, such as quantum teleportation and quantum computation. Research on quantifying entangled states has been carried out using several measures. In this Letter, we will adopt this method using quantum mutual entropy to measure the degree of entanglement in the time development of the Jaynes-Cummings model.
