摘要：
迄今为止，对单光子复杂时空量子波函数的无约束控制仍然难以实现，尽管这种控制能够显著提升编码灵活性，从而提高光子量子链路的信息容量。通过融合冷原子系综中的时间波形产生与空间单光子整形，我们在此首次展示了对传播不变的 (2+1)D Airy 单光子光学子弹的完全时空控制。这些关联光子不仅与其经典对应物一样具有自加速特性且不会扩散，还能够在强经典光噪声存在时被隐藏和显现。我们的方法可稳健且通用地合成任意量子非扩散时空光子弹；在这方面，它可能对量子成像、长距离量子通信和多维信息编码等广泛应用产生影响。
英文摘要：
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.
