论文摘要
在目前的工作中，将平均保真度作为转向参数。根据从爱丽丝到鲍勃的转向的定义，为高维系统开发了设计线性转向标准的一般方案。对于鲍勃（Bob）侧面的一组测量值，可以定义两个数量，即所谓的非稳定阈值。如果测得的平均保真度超过了这些阈值，则爱丽丝和鲍勃共享的状态是从爱丽丝到鲍勃的，并且爱丽丝执行的测量值也已被证实是不相容的。在一般方案中，当Bob执行的一组测量值连续设置时，我们还构建了线性转向不等式。还提供了一些应用程序。
In the present work, the averaged fidelity is introduced as the steering parameter. According to the definitions of steering from Alice to Bob, a general scheme for designing linear steering criteria is developed for a high-dimensional system. For a given set of measurements on Bob's side, two quantities, the so-called nonsteering thresholds, can be defined. If the measured averaged fidelity exceeds these thresholds, the state shared by Alice and Bob is steerable from Alice to Bob, and the measurements performed by Alice are also verified to be incompatible. Within the general scheme, we also construct a linear steering inequality when the set of measurements performed by Bob has a continuous setting. Some applications are also provided.
