在本文中,我们介绍了一个简单而自然的二分贝尔场景,通过考虑两方之间的相关性定义的一般测量在一方和二分法的其他。我们表明,在这种情况下,可以得到无界贝尔违反。由于当双方都使用二分测量时不会发生这种违反,因此我们的设置可以被认为是可以观察到这种现象的最简单的设置。我们的例子在输出和希尔伯特空间维数方面基本上是最优的。
In this paper we introduce a simple and natural bipartite Bell scenario, by considering the correlations between two parties defined by general measurements in one party and dichotomic ones in the other. We show that unbounded Bell violations can be obtained in this context. Since such violations cannot occur when both parties use dichotomic measurements, our setting can be considered as the simplest one where this phenomenon can be observed. Our example is essentially optimal in terms of the outputs and the Hilbert space dimension.
