Self-testing is a method to verify that one has a particular quantum state from purely classical statistics. For practical applications, such as device-independent delegated verifiable quantum computation, it is crucial that one self-tests multiple Bell states in parallel while keeping the quantum capabilities required of one side to a minimum. In this work, we use the $3 \times n$ magic rectangle games (generalizations of the magic square game) to obtain a self-test for $n$ Bell states where the one side needs only to measure single-qubit Pauli observables. The protocol requires small input sizes [constant for Alice and $O(\log n)$ bits for Bob] and is robust with robustness $O(n^{5/2} \sqrt{\varepsilon})$, where $\varepsilon$ is the closeness of the ideal (perfect) correlations to those observed. To achieve the desired self-test, we introduce a one-side-local quantum strategy for the magic square game that wins with certainty, we generalize this strategy to the family of $3 \times n$ magic rectangle games, and we supplement these nonlocal games with extra check rounds (of single and pairs of observables).

局域实在论已经被基于贝尔定理的纠缠粒子实验所推翻。Bell，Physics（Long Island City，N.Y.）1，195（1964））。然而，关于问题是局部性还是现实性的争论一直在继续。在这项工作中，我们分析了爱因斯坦-波多尔斯基-罗森思想实验玻姆的版本，用信息论和热力学。从EPR实验中推断非定域性将违背量子力学的非实在性原理。因此，有关量子纠缠的实验不能提供任何证据来指责局域性。
