论文摘要
自由空间量子密钥分布已成为远程量子通信的领先平台的兴趣越来越大。然而，量子相关对散射的敏感性由湍流大气链路引起的散射限制了此类系统的性能。最近，已经证明了补偿纠缠光子散射的方法，从而可以实时优化其量子相关性。在这封信中，我们证明了波前形状用于补偿非结合和非分级纠缠光子的散射。这些结果证明了使用纠缠光子的较大带宽和发射角度，波前塑形方案适用于协议。
Free-space quantum key distribution is gaining increasing interest as a leading platform for long range quantum communication. However, the sensitivity of quantum correlations to scattering induced by turbulent atmospheric links limits the performance of such systems. Recently, methods for compensating the scattering of entangled photons have been demonstrated, allowing for real-time optimization of their quantum correlations. In this Letter, we demonstrate the use of wavefront shaping for compensating the scattering of non-collinear and non-degenerate entangled photons. These results demonstrate the applicability of wavefront shaping schemes for protocols utilizing the large bandwidth and emission angle of the entangled photons.
