论文摘要
这项工作根据光纤的陆地铺设提供了一种卫星替代方案，后者具有以下缺点：繁殖速度（v）等于光速的2/3（v），损失（c）的损失，损失和衰减需要在材料中占用更少的材料，而在每一个范围内都需要覆盖的速度，同时又可以覆盖重复的范围，同时又有范围的转折，同时又可以覆盖重复的范围，而均可供应量的速度。在光纤的情况下，除了与地面链接的相对环境方面，即可能破坏纠缠光子分布的云。提出了两种配置，这是卫星的第一个配置，如果地面上的两个点无法访问同一卫星，则两个卫星中的第二个配置。最后，一系列用于评估两种配置的性能和鲁棒性的实现，在5 QUBITS IBM Q处理器上实现。
This work presents a satellite alternative to quantum repeaters based on the terrestrial laid of optical fiber, where the latter have the following disadvantages: a propagation speed (v) equal to 2/3 of the speed of light (c), losses and an attenuation in the material that requires the installation of a repeater every 50 km, while satellite repeaters can cover greater distances at a speed v = c, with less attenuation and losses than in the case of optical fiber except for relative environmental aspects to the ground-sky link, i.e., clouds that can disrupt the distribution of entangled photons. Two configurations are presented, the first one of a satellite and the second one of two satellites in the event that both points on the ground cannot access the same satellite. Finally, a series of implementations for evaluating the performance and robustness of both configurations are implemented on a 5 qubits IBM Q processor.
