One of the basic building blocks of quantum mechanics and quantum information science is the photon, the smallest possible amount of light. Unfortunately, photons can be made to interact (i.e., "talk to each other") only through matter. The implementation of such single-photon interactions is thus the topic of much fundamental and applied research efforts. Classically, interacting ("nonlinear") single photons constitute the fundamental limit of low-power optical switches, transistors, modulators, etc. On the quantum level, they provide the building blocks for quantum-enhanced technology and the so-called "third quantum revolution." The proposed work suggests 2D ordered arrays of atoms in traps. If these atoms are close enough to each other, they provide excellent effective photon interactions and are highly controllable.This project introduces a novel interaction platform that takes advantage of intrinsically nonlinear quantum media that can enhance single-photon nonlinearities such as cooperative and subradiant systems. Furthermore, adding an impurity to a cooperative 2D array allows light to couple to the medium, introducing a “quantum antenna.” Photons coupling to several such impurities can in this setup interact through the medium even stronger. Further enhancement can be reached through integration of Rydberg levels of the atoms or by additionally modifying the response of the material to display, e.g., a zero index of refraction. The questions that will be answered in this work are: (i) How can nonlinear material help create and harvest nonlinear interactions between photons? (ii) How, conversely, can photons be used to control cooperative materials? (iii) How can one implement these concepts experimentally and what applications are possible? Possible applications include quantum information processing, metrology, and quantum metamaterials, i.e., a class of materials exhibiting inherent quantum material response to light.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

量子力学和量子信息科学的基本构件之一是光子，它是光的最小可能数量。不幸的是，只有通过物质才能使光子相互作用(即“相互交谈”)。因此，这种单光子相互作用的实现是许多基础和应用研究工作的主题。经典地说，相互作用的(“非线性”)单光子构成了低功率光开关、晶体管、调制器等的基本极限。在量子层面上，它们为量子增强技术和所谓的“第三次量子革命”提供了基石。这项拟议的工作提出了陷阱中原子的2D有序阵列。如果这些原子彼此足够近，它们就会提供极好的有效光子相互作用，并且高度可控。这个项目引入了一个新的相互作用平台，该平台利用了本质上的非线性量子介质，可以增强单光子非线性，如合作和亚辐射系统。此外，在合作的2D阵列中添加杂质可以使光耦合到介质上，从而引入一种“量子天线”。在这种情况下，耦合到几个这样的杂质的光子可以通过介质进行更强的相互作用。可以通过对原子的里德堡能级进行积分或者通过附加地修改材料的响应以显示例如零折射率来实现进一步的增强。这项工作将回答的问题是：(I)非线性材料如何帮助创造和收获光子之间的非线性相互作用？(2)反过来，如何利用光子来控制合作材料？(3)如何在实验中实施这些概念，以及哪些应用是可能的？可能的应用包括量子信息处理、计量学和量子超材料，即一类表现出固有的量子材料对光的响应的材料。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
