eng entropy measure of quantum entanglement
本文基于邓熵提出了度量量子纠缠度的方法。分别计算纠缠态和解纠缠之后状态的最大邓熵，将两个熵之差作为纠缠度度量。用GHZ和W纠缠态作为算例给出了所提出方法的应用。
" How to measure quantum entanglement is still an open issue. Some entropy functions are applied to address this issue, such as von neumann entropy. In this paper, a new Deng entropy based method is presented to measure quantum entanglement. The main idea is calculation the entropy difference between the state of entanglement and the state of disentanglement as the quantum entanglement degree. The more the entropy difference, the less the quantum entanglement degree. Numerical examples on two typical quantum entanglement, namely GHZ state and W state, are illustrated the efficiency of the proposed Deng entropy measure.
