非定域性资源理论与非定域性测度

On nonlocality as a resource theory and nonlocality measures

Julio I. de Vicente

摘要:

随着与设备无关的量子信息处理的出现,非局域性被认为是实现各种任务的资源。在纠缠理论的类比中,我们从这个角度来研究非定域性。为了做到这一点,我们详细分析了在这种情况下可以实现的操作,并且在这种情况下,非局部性不能增加。这为研究如何对非局部行为进行排序和量化提供了理论基础。最后,我们回顾了几个非局部性措施,并从这个角度讨论他们的有效性。

英文摘要:

With the advent of device independent quantum information processing, nonlocality is nowadays regarded as a resource to implement various tasks. On the analogy of entanglement theory we approach nonlocality from this perspective. In order to do so, we analyze in full detail the operations that can be implemented in this scenario and under which nonlocality cannot increase. This provides a theoretical ground to study how to order and quantify nonlocal behaviours. Finally, we review several nonlocality measures and discuss their validity from this point of view.
