具有亚波长间隔的有序原子阵列已经成为一种高效和通用的光-物质界面，其中发射器集体响应并形成具有抑制衰减率的子辐射晶格模式。在这里，我们证明了这种晶格暗态可以通过应用原子失谐的空间调制来单独寻址和操纵。更具体地说，我们证明了晶格暗态可以用于以近单位效率存储和检索单个光子，以及控制发射电磁场的时间，频率和空间自由度。此外，我们还讨论了如何在多个暗态之间设计任意相干相互作用。这些结果为构建一个量子平台铺平了道路，该平台既可以作为量子存储器，也可以作为能够产生量子信息协议中相关光态的光子成形器。
Ordered atomic arrays with subwavelength spacing have emerged as an efficient and versatile light-matter interface, where emitters respond collectively and form subradiant lattice modes with supressed decay rate. Here, we demonstrate that such lattice dark states can be individually addressed and manipulated by applying a spatial modulation of the atomic detuning. More specifically, we show that lattice dark states can be used to store and retrieve single photons with near-unit efficiency, as well as to control the temporal, frequency and spatial degrees of freedom of the emitted electromagnetic field. Additionally, we discuss how to engineer arbitrary coherent interactions between multiple dark states. These results pave the way towards building a quantum platform that can equally act as a quantum memory and a photon shaper capable of producing states of light relevant in quantum information protocols.
