Title: 基于1550 nm超相关光的噪声容限相关符合成像

Abstract: Single-photon-level imaging at 1550 nm is a key driver for significant advancements in the next-generation laser detection technology. This cutting-edge approach plays a vital role in space ranging, target recognition, and three-dimensional remote sensing. However, it has faced severe challenges such as insufficient noise-tolerant performance. Here, we introduced noise-tolerant correlated coincidence imaging (CCI) based on super-correlated light. The light source, generated through nonlinear interaction between a pulsed laser and a photonic crystal fiber, exhibits a broader power-law photon number probability distribution and extremely strong photon correlation (with second-order correlation function $g^{(2)}(0)$ up to 18,166). Our noise-tolerant CCI can resist random environmental noise up to 100,000 times stronger than the echo signal photons. Super-correlated light offers an exceptionally strong noise tolerance for single-photon-level imaging in extreme environments with intense noise, paving the way for the future development of extremely sensitive light detection.

Abstract: 在1550纳米波长下实现单光子级成像，是推动下一代激光探测技术显著进步的关键因素。这种前沿方法在空间测距、目标识别和三维遥感中起着至关重要的作用。然而，它面临着诸如噪声容忍性能不足等严峻挑战。在此，我们引入了一种基于超相关光的噪声容忍相关符合成像（CCI）。该光源通过脉冲激光与光子晶体光纤之间的非线性相互作用生成，表现出更宽的幂律光子数概率分布和极强的光子关联性（二阶关联函数$g^{(2)}(0)$最高达18,166）。我们的噪声容忍CCI能够抵抗比回波信号光子强达100,000倍的随机环境噪声。超相关光为在强噪声极端环境中实现单光子级成像提供了极其强大的噪声容忍能力，为极高灵敏度光探测的未来发展铺平了道路。
