论文摘要
光纤传输系统构成了当今通信网络的骨干，对于未来的网络也将非常重要。光纤中显着的噪声效应是相位噪声，该噪声是由KERR效应诱导的。这种效果限制了这些网络的数据传输能力，并在接收器上造成了高处理负载。同时，量子信息处理技术提供了更有效的解决方案，但据信在大小，功耗和对噪声的抵抗方面效率低下。在这里，我们研究了全光关节检测接收器的概念。我们展示了它如何在用作前处理器时，即使在Kerr效应引起的高噪声下，它如何为光学传输系统促进更高的波特速率。
Optical fiber transmission systems form the backbone of today's communication networks and will be of high importance for future networks as well. Among the prominent noise effects in optical fiber is phase noise, which is induced by the Kerr effect. This effect limits the data transmission capacity of these networks and incurs high processing load on the receiver. At the same time, quantum information processing techniques offer more efficient solutions but are believed to be inefficient in terms of size, power consumption and resistance to noise. Here we investigate the concept of an all-optical joint detection receiver. We show how it contributes to enabling higher baud-rates for optical transmission systems when used as a pre-processor, even under high levels of noise induced by the Kerr effect.
