论文摘要
强大的局部被动性是多片量子系统的特性，无法从本地提取能量。令人惊讶的是，如果强大的局部被动状态显示纠缠，则可以通过所谓的“量子能量传送”协议通过在系统的不同分区之间添加经典通信来局部激活能量密度。在这里，我们报告了对纠缠状态上能量密度的局部激活的第一个实验性观察，也报告了使用核磁共振上的两分部分量子系统对量子能传送方案的首次实现。
Strong local passivity is a property of multipartite quantum systems from which it is impossible to extract energy locally. Surprisingly, if the strong local passive state displays entanglement, it could be possible to locally activate energy density by adding classical communication between different partitions of the system, through so-called "quantum energy teleportation" protocols. Here, we report both the first experimental observation of local activation of energy density on an entangled state and the first realization of a quantum energy teleportation protocol using nuclear magnetic resonance on a bipartite quantum system.
