论文摘要
我们考虑由Ising Hamiltonian进化运营商生成的图形状态。分析并在IBM的量子计算机IBM Q Valencia上获得了与图形状态中其他自旋的纠缠的几何测量。量子计算的结果与理论上的结果非常吻合。我们得出的结论是，图表状态中自旋与其他旋转的纠缠的几何测量与表示相应图中的自旋的角度有关。
We consider graph states generated by operator of evolution with Ising Hamiltonian. The geometric measure of entanglement of a spin with other spins in the graph state is obtained analytically and quantified on IBM's quantum computer, IBM Q Valencia. The results of quantum calculations are in good agreement with the theoretical ones. We conclude that the geometric measure of entanglement of a spin with other spins in the graph state is related with degree of vertex representing the spin in the corresponding graph.
