标题： Entanglement and maximal violation of the CHSH inequality in a system of two spins j: a novel construction and further observations

摘要： 我们研究两个自旋$j$粒子系统的 CHSH 不等式，对于一般的$j$。 CHSH 算子是使用一组单位的、厄米的算子$\left\{ A_{1},A_{2},B_{1},B_{2}\right\} $构造的。 CHSH 算子的期望值在单态$\left|\psi_{s}\right\rangle $中进行了分析。 作为$\left|\psi_{s}\right\rangle $一个纠缠态，发现与 Tsirelson 的界限相容的 CHSH 不等式的违反。 尽管这里采用的构造与 [1] 中的不同，但完全一致的结果被恢复。 显示英文摘要

摘要： We study the CHSH inequality for a system of two spin $j$ particles, for generic $j$. The CHSH operator is constructed using a set of unitary, Hermitian operators $\left\{ A_{1},A_{2},B_{1},B_{2}\right\} $. The expectation value of the CHSH operator is analyzed for the singlet state $\left|\psi_{s}\right\rangle $. Being $\left|\psi_{s}\right\rangle $ an entangled state, a violation of the CHSH inequality compatible with Tsirelson's bound is found. Although the construction employed here differs from that of [1], full agreement is recovered.
