论文摘要
到目前为止，对单个光子的复杂时空量子波函数的不受限制控制仍然难以捉摸，即使它可以显着提高编码的灵活性，从而使光子量子链路的信息能力。通过在冷原子集合和空间单光子形状中融合时间波形的产生，我们在此首次证明了传播不变（2+1）d通风单光子子弹的完全时空控制。这些相关的光子不仅是自动加速的，而且不渗透为传播作为其经典对应物，而且可以在存在强大的经典光噪声的情况下隐藏和揭示。我们的方法允许人们以强大而多功能的方式合成任意量子非时空的光子子弹，在这方面，可能会在诸如量子成像，长距离量子通信和多维信息编码等广泛应用中产生后果。
Uninhibited control of the complex spatiotemporal quantum wavefunction of a single photon has so far remained elusive even though it can dramatically increase the encoding flexibility and thus the information capacity of a photonic quantum link. By fusing temporal waveform generation in a cold atomic ensemble and spatial single-photon shaping, we hereby demonstrate for the first time complete spatiotemporal control of a propagation invariant (2+1)D Airy single-photon optical bullet. These correlated photons are not only self-accelerating and impervious to spreading as their classical counterparts, but can be concealed and revealed in the presence of strong classical light noise. Our methodology allows one to synthesize in a robust and versatile manner arbitrary quantum nonspreading spatiotemporal light bullets and in this respect could have ramifications in a broad range of applications such as quantum imaging, long-distance quantum communications, and multidimensional information encoding.
