摘要:

近年来,人们对跨越全球的量子网络给予了极大的关注,包括用于从量子密钥分发到分布式传感器和时钟的应用的链接卫星。在许多这些方案中,相对论变换可能对分布式纠缠对的纯度产生有害影响。这对于分布式时钟的应用变得特别重要。在本文中,我们开发了一个洛伦兹不变的纠缠分配协议,完全消除了由于相对运动的卫星的影响。

英文摘要:

In recent years there has been a great deal of focus on a globe-spanning quantum network, including linked satellites for applications ranging from quantum key distribution to distributed sensors and clocks. In many of these schemes, relativistic transformations may have deleterious effects on the purity of the distributed entangled pairs. This becomes particularly important for the application of distributed clocks. In this paper, we have developed a Lorentz invariant entanglement distribution protocol that completely removes the effects due to the relative motions of the satellites.
