非定域量子关联的单偶性

Monogamy of nonlocal quantum correlations

Ben Toner

摘要:

我们描述了一种新的技术获得Tsirelson界,或上界的量子值的贝尔不等式。由于量子关联不允许信号,我们通过最大化所有无信号概率分布来获得Tsirelson界。这种最大化可以被看作是一个线性规划。在三方A、B和C共享任意维度的纠缠量子态的情况下,我们:(i)约束AB和AC违反CHSH不等式之间的权衡,以及(ii)证明强迫B和C经典相关可以防止A和B违反某些贝尔不等式,这与交互式证明系统和密码学有关。

英文摘要:

We describe a new technique for obtaining Tsirelson bounds, or upper bounds on the quantum value of a Bell inequality. Since quantum correlations do not allow signaling, we obtain a Tsirelson bound by maximizing over all no-signaling probability distributions. This maximization can be cast as a linear program. In a setting where three parties, A, B, and C, share an entangled quantum state of arbitrary dimension, we: (i) bound the trade-off between AB's and AC's violation of the CHSH inequality, and (ii) demonstrate that forcing B and C to be classically correlated prevents A and B from violating certain Bell inequalities, relevant for interactive proof systems and cryptography.
