论文摘要
我们从量子的角度考虑全光网络的演变。我们表明，最佳量子接收器的使用允许估计$ 55 \％$ $减少当今典型的网络配置中全光放大器的能源消耗。然后，我们将量子接收器的数据传输能力与当今技术在香农设定的边界内运行。我们发现，量子接收器技术允许与波特速率进行对数缩放系统容量的对数缩放，而香农型系统则受到传输功率的限制。因此，出现了经典数据传输的自然量子限制。基于上述发现，我们主张一种新的光学通信网络设计方法，其中在线放大器被新颖的纤维替换为支持高光谱带宽的新型纤维，以允许在量子限制中进行无噪声数据传输。
We consider all-optical network evolution from a quantum perspective. We show that a use of optimal quantum receivers allows an estimated $55\%$ decrease in energy consumption of all-optical amplifiers in network configurations that are typical today. We then compare data transmission capacities of quantum receivers with today's technology operating within the boundaries set by Shannon. We find that quantum receiver technology allows for a logarithmic scaling of the system capacity with the baud-rate, while Shannon-type systems are limited by the transmit power. Thus a natural quantum limit of classical data transmission emerges. Based on the above findings we argue for a new approach to optical communication network design, wherein in-line amplifiers are replaced by novel fiber supporting high spectral bandwidth to allow for noiseless data transmission in the quantum limit.
