在一般量子网络上实现与设备无关的信息处理

Towards device-independent information processing on general quantum networks

Ciarán M. Lee, Matty J. Hoban

摘要:

某些贝尔不等式的违反允许设备无关的信息处理安全地对抗非信令窃听者。然而,这只适用于贝尔网络,在贝尔网络中,两个或多个代理对一个共享的纠缠源进行本地测量。为了克服纠缠系统只能在相对短的距离内传输的实际限制,已经采用了大规模的多源网络。是否存在类似的贝尔不等式的这种网络,其违反是一个资源的设备无关性?在本文中,违反最近派生的多项式贝尔不等式将被证明允许设备独立的多源网络,对非信令窃听安全。

英文摘要:

The violation of certain Bell inequalities allows for device-independent information processing secure against non-signalling eavesdroppers. However, this only holds for the Bell network, in which two or more agents perform local measurements on a single shared source of entanglement. To overcome the practical constraint that entangled systems can only be transmitted over relatively short distances, large-scale multi-source networks have been employed. Do there exist analogues of Bell inequalities for such networks, whose violation is a resource for device-independence? In this paper, the violation of recently derived polynomial Bell inequalities will be shown to allow for device-independence on multi-source networks, secure against non-signalling eavesdroppers.
