标题： Characterizing nonlocal dispersion compensation in deployed telecommunications fiber

摘要： 宽带光子对在已部署的电信光纤中的传播用于实现非局域色散补偿，而无需特意引入负色散。 这是通过利用时间-能量纠缠以及光纤的正负色散特性来实现的。 我们展示了在经过两个多段10公里的已部署光纤传输后，以及最多80公里的实验室光纤传输后，光子时间相关性得到了保持。 显示英文摘要

摘要： Propagation of broadband photon pairs over deployed telecommunication fibers is used to achieve nonlocal dispersion compensation without the deliberate introduction of negative dispersion. This is made possible by exploiting time-energy entanglement and the positive and negative dispersive properties of the fiber. We demonstrate preservation of photon timing correlations after transmission over two multi-segment 10km spans of deployed fiber and up to 80km of laboratory-based fiber.
