论文摘要
根据人们的测量方式，量子非局部性可能会更明显地表现出来。在逻辑上，Hardy使用基础转换和相互作用，认为任何局部隐藏变量理论都会导致悖论。从原始工作延伸，我们使用两种不同的方法引入了针对N粒子系统的量子非本地方案。首先，得出了一个理论模型，其分析结果是Hardy的非局部性条件和概率。其次，构建了使用量子电路的量子模拟，与分析理论非常匹配。当在n = 3的实际量子计算机上证明时，与理论相比，我们获得了合理的结果。即使在宏观尺度上随着n的成长，成功概率渐近线也15.6％，这比以前的结果强。
Depending on the way one measures, quantum nonlocality might manifest more visibly. Using basis transformations and interactions on a particle pair, Hardy logically argued that any local hidden variable theory leads to a paradox. Extended from the original work, we introduce a quantum nonlocal scheme for n-particle systems using two distinct approaches. First, a theoretical model is derived with analytical results for Hardy's nonlocality conditions and probability. Second, a quantum simulation using quantum circuits is constructed that matches very well to the analytical theory. When demonstrated on real quantum computers for n=3, we obtain reasonable results compared to theory. Even at macroscopic scales as n grows, the success probability asymptotes 15.6%, which is stronger than previous results.
