Jamming Extensions of Quantum Correlations Lead to Hidden Superluminal Signaling

该研究通过扩展算子框架刻画符合相对论因果性的关联，证明量子关联的非平凡干扰会导致隐藏超光速信号，并构造RC攻击破坏设备无关密码原语的安全性，指出安全性需结合测量事件的时空位置。

Action and Passion at a Distance: An Essay in Honor of Professor Abner Shimony

Quantum mechanics permits nonlocality---both nonlocal correlations and nonlocal equations of motion---while respecting relativistic causality. Is quantum mechanics the unique theory that reconciles nonlocality and causality? We consider two models, going beyond quantum mechanics, of nonlocality---``superquantum" correlations, and nonlocal ``jamming" of correlations---and derive new results for the jamming model. In one space dimension, jamming allows reversal of the sequence of cause and effect; in higher dimensions, however, effect never precedes cause.
