在我们的论文中，我们证明了一个双qutrit Werner态在每站点两个投影测量、每次测量三个结果的场景中，对所有参数值都允许一个局域隐变量模型。为此，我们推导了一个简单的充分条件，在该条件下，一个双qutrit态对于Alice和Bob的任意可观测量的选择满足Collins-Gisin-Linden-Massar-Popescu不等式，并证明Werner态总是满足此条件。接下来，我们利用这样一个事实：任何对于Alice和Bob的任意可观测量的选择满足Collins-Gisin-Linden-Massar-Popescu不等式的双qutrit态都允许一个局域隐变量模型。
英文摘要
In our paper, we show that a two-qutrit Werner state admits a local hidden-variable model for all values of the parameter in a scenario involving two projective measurements per site, with three outcomes per measurement. To this end, we derive a simple sufficient condition under which a two-qutrit state satisfies the Collins-Gisin-Linden-Massar-Popescu inequality for arbitrary choices of Alice's and Bob's observables, and show that the Werner state always satisfies this condition. Next, we use the fact that any two-qutrit state satisfying the Collins-Gisin-Linden-Massar-Popescu inequality for arbitrary choices of Alice's and Bob's observables admits a local hidden variable model.
