Non-technical abstract: Two-dimensional (2D) crystals are a new class of materials that measure only a few nanometers in thickness. Recent studies have shown that these materials offer unique advantages over other known materials, and that they hold the potential to make a large impact in new-generation electronics, energy conversion, and storage applications. When these 2D crystals are stacked onto each other they form a material known as a 2D Moire superlattice, which possesses an unusual physical properties that may enable quantum computation. Such materials could revolutionize current information technologies. This research aims to reach a fundamental understanding of the optical behavior of 2D Moire superlattices using advanced optical measurement techniques, as well as develop state-of-the-art fabrication techniques to create nanoscale devices for manipulation of quantum information. The research activities have significant impact on training of next-generation researchers. Doctoral and master students, as well as undergraduates conduct all the necessary experiments, participating in hands-on research activities. The research team is preparing YouTube videos: 'Moire patterns in the nature, science, and engineering' and '2D Moire superlattices and 2D crystals', to reach out to the general public and science/technology enthusiasts. Exciting results are also shared through conference presentations, journal publications, and scientific review articles. Technical abstract: A quantum emitter strongly coupled to a cavity that operates down to the single-photon level is essential for quantum logic. Yet, there have been big challenges to achieve this at room temperature due to the limited coupling strength between conventional quantum emitters and optical cavities . This research explores the quantum optics of Moire quantum emitters (Moire-QEs) as single-photon emitters and their integration with Fano-dielectric metacavities, allowing manipulation of coherent states in quantum logic operations. The research projects include; i) the synthesis of optical grade, highly crystalline, and atomically clean Moire superlattices sustaining long-lived Moire-QEs through CVD and MBE methods, ii) investigation of quantum optics of Moire-QEs to identify their potential in quantum logic operation; iii) designing low-loss, high-Q, and large Rabi energy splitting metacavities, fabricating them, and integrating them with Moire-QEs to enable quantum logic operation, and lastly iv) investigation of nonlinear effects and demonstration of cross-phase modulation. The research is anticipated to lay a solid foundation towards creating large periodicity Moire-QEs and to understand their behavior related to single photon nonlinearities. In addition, the project aims to identify clear pathways towards potentially scalable quantum system design, to study room temperature quantum optical nonlinear effects, and quantum state manipulations.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.

非技术摘要：二维（2D）晶体是一类新的材料，仅测量厚度的少数纳米。最近的研究表明，这些材料比其他已知材料具有独特的优势，并且它们具有对新代电子，能源转换和存储应用产生巨大影响的潜力。当这些2D晶体彼此堆叠时，它们形成一种称为2D Moire Super晶格的材料，该材料具有不寻常的物理特性，可以实现量子计算。这样的材料可以彻底改变当前的信息技术。这项研究旨在使用先进的光学测量技术对2D Moire超级晶格的光学行为进行基本了解，并开发最新的制造技术，以创建纳米级设备来操纵量子信息。研究活动对下一代研究人员的培训有重大影响。博士和硕士学生以及本科生进行所有必要的实验，参加动手研究活动。研究团队正在准备YouTube视频：“自然，科学和工程学中的Moire模式”和“ 2D Moire Supertatices和2D Crystals”，以与公共和科学/技术爱好者接触。令人兴奋的结果也通过会议演讲，期刊出版物和科学评论文章分享。技术摘要：一个量子发射极与单光子水平的腔体紧密耦合对于量子逻辑至关重要。然而，由于常规量子发射器和光腔之间的耦合强度有限，因此在室温下实现这一目标存在巨大挑战。这项研究探讨了Moire量子发射器（Moire-QE）作为单光子发射器的量子光学，及其与Fano-Dileclectric Metacavities的集成，从而可以在量子逻辑操作中操纵相干状态。研究项目包括； i）通过CVD和MBE方法持续长期寿命的Moire-QE的光学等级，高度结晶和原子清洁的Moire超级晶格，ii）研究Moire-Qes的量子光学量，以识别其在量子逻辑运行中的潜力； iii）设计低损坏，高Q和大型Rabi Energy裂解元模腔，制造它们，并将它们与Moire-Qes集成以实现量子逻辑操作，最后是IV）研究非线性效应并证明了跨相调制。预计这项研究将为创建大量的周期性Moire-Qes奠定坚实的基础，并了解其与单个光子非线性有关的行为。此外，该项目旨在确定通往潜在的可扩展量子系统设计的清晰途径，研究室温量子量子光学非线性效应和量子状态操作。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的审查标准来通过评估来进行评估的。
