RAISE-EQuIP:Quantum Mux/Demux: The Quantum Optical Frequency Comb as a Scalable Quantum Encoding Resource Quantum information and quantum computing are emerging fields that have the potential to revolutionize various areas in science and technology. As first foreseen by Richard Feynman, quantum computers will enable calculations at currently unattainable scales and will bring unprecedented advances over classical computers. Examples include calculations of large biological molecules for revolutionary drug discovery, solving complex quantum mechanical systems, and factoring integers at a speed exponentially faster than classical computer to defeat current standard encryption methods. Quantum information is also fundamentally distinct from classical information. It cannot be cloned or hacked and therefore brings new power for cryptography, such as the method of quantum key distribution to create secure communications channels. The realization of practical systems capable of quantum computing and information is an extraordinary difficult task but will have profound impacts on national security and our society. To date, two primary challenges have been identified in making quantum technology a reality: achieving scalability and circumventing decoherence. At this juncture, many proof-of principle results have been experimentally demonstrated to address either decoherence (trapped-ion, superconducting, and cold atom qubits), or the scalability problem (field qumodes), but both requirements have not been met simultaneously yet. This project will address both of these challenges by a joint interdisciplinary effort between the Electrical and Computer Engineering and the Physics Departments at University of Virginia by ways of scalable integrated quantum photonics.The aim of this project is to marry scalable integrated photonics with quantum information and quantum computation over continuous variables in order to encode quantum information over the quantum optical frequency comb (QOFC). Such technology will empower unconditional quantum protocols such as quantum communication, quantum entanglement distillation, and quantum simulation. With NSF support, the quantum optics group at the University of Virginia has been pioneering the implementation of QOFC in optical parametric oscillator and has achieved record-levels of multipartite entanglements (60 qumodes). Integrated microresonator-based optical frequency combs, heterogeneous photonic integration and near unity quantum efficiency photodiodes have been in the focus of research in the micro-photonics, optoelectronic and photonics device groups at UVA for many years. The project aims to combine these efforts and create a unique integrated device on a chip with multimode quantum emitter, qumodes processing and detection. Such a realization enables numerous quantum applications on a chip, including massively scalable cluster entanglement, scalable deterministic quantum processing, quantum secret sharing over QOFC, and quantum mode sorting.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.

RAISE-EQuIP：量子Mux/Demux：量子光学频率梳作为可扩展的量子编码资源量子信息和量子计算是新兴领域，有可能彻底改变科学和技术的各个领域。正如理查德·费曼（Richard Feynman）首先预见的那样，量子计算机将实现目前无法实现的规模计算，并将带来比经典计算机前所未有的进步。例子包括用于革命性药物发现的大型生物分子的计算，解决复杂的量子力学系统，以及以比经典计算机更快的速度分解整数以击败当前标准加密方法。量子信息也从根本上不同于经典信息。它不能被克隆或黑客攻击，因此为密码学带来了新的力量，例如量子密钥分发方法来创建安全的通信通道。实现具有量子计算和信息能力的实用系统是一项非常艰巨的任务，但将对国家安全和我们的社会产生深远影响。迄今为止，在使量子技术成为现实的过程中，已经确定了两个主要挑战：实现可扩展性和规避退相干。在这个关键时刻，许多原理证明结果已经被实验证明可以解决退相干（捕获离子、超导和冷原子量子比特）或可扩展性问题（场量子模），但这两个要求还没有同时满足。该项目将通过弗吉尼亚大学电子与计算机工程系和物理系之间的跨学科合作，通过可扩展集成量子光子学的方式解决这两个挑战。该项目的目的是将可扩展集成光子学与量子信息和连续变量上的量子计算结合起来，以便在量子光学频率梳（QOFC）上编码量子信息。这种技术将使量子通信、量子纠缠蒸馏和量子模拟等无条件量子协议成为可能。在美国国家科学基金会的支持下，弗吉尼亚大学的量子光学小组率先在光学参量振荡器中实现了QOFC，并实现了创纪录的多部纠缠（60个模）。多年来，基于集成微谐振器的光频率梳、异质光子集成和近单位量子效率光电二极管一直是UVA微光子学、光电子和光子学器件组的研究热点。该项目旨在将这些努力结合起来，在芯片上创建一个独特的集成设备，具有多模量子发射器，模处理和检测。这样的实现可以在芯片上实现许多量子应用，包括大规模可扩展的集群纠缠、可扩展的确定性量子处理、QOFC上的量子秘密共享和量子模式排序。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
