全光腔网络中噪声辅助传输的观测

Observation of noise-assisted transport in an all-optical cavity-based network

Silvia Viciani, Manuela Lima, Marco Bellini, Filippo Caruso

摘要:

最近的理论和实验工作表明,噪声在提高复杂系统的传输效率方面具有显著的和违反直觉的作用。在这里,我们实现了简单的,可扩展的,可控的光纤腔网络,使我们能够分析传输网络的性能为不同的条件下的干扰,失相和混乱。特别是,我们的实验表明,运输效率达到最大值时,改变外部失相噪声,即一个钟形的行为,已经预测只有理论上。这些光学平台是非常有前途的量子输运现象的模拟器,特别是可以用于设计和测试未来太阳能技术的人工捕光结构的最佳拓扑结构。

英文摘要:

Recent theoretical and experimental efforts have shown the remarkable and counter-intuitive role of noise in enhancing the transport efficiency of complex systems. Here, we realize simple, scalable, and controllable optical fiber cavity networks that allow us to analyze the performance of transport networks for different conditions of interference, dephasing and disorder. In particular, we experimentally demonstrate that the transport efficiency reaches a maximum when varying the external dephasing noise, i.e. a bell-like shape behavior that had been predicted only theoretically. These optical platforms are very promising simulators of quantum transport phenomena, and could be used, in particular, to design and test optimal topologies of artificial light-harvesting structures for future solar energy technologies.
