    "abstract": "In this paper, we present a generalized Bell inequality for mixed states. The\ndistinct characteristic is that the inequality has variable bound depending on\nthe decomposition of the density matrix. The inequality has been shown to be\nmore refined than the previous Bell inequality. It is possible that a separable\nmixed state can violate the Bell inequality.",
