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：量子复用/解复用：量子光频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技术的各个领域。正如理查德·费曼 (Richard Feynman) 首次预见的那样，量子计算机将实现目前无法达到的规模计算，并将带来相对于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快指数的速度分解整数以击败当前的标准加密方法。量子信息也与经典信息有着根本的区别。它无法被克隆或黑客攻击，因此为密码学带来了新的力量，例如用于创建安全通信通道的量子密钥分发方法。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。目前，许多原理证明结果已通过实验证明可以解决退相干（俘获离子、超导和冷原子量子位）或可扩展性问题（场量子模式），但这两个要求尚未同时满足。该项目将通过弗吉尼亚大学电气和计算机工程以及物理系之间的跨学科联合努力，通过可扩展的集成量子光子学来解决这两个挑战。该项目的目的是将可扩展的集成光子学与量子信息结合起来对连续变量进行量子计算，以便通过量子光学频率梳（QOFC）对量子信息进行编码。此类技术将为无条件量子协议提供支持，例如量子通信、量子纠缠蒸馏和量子模拟。在 NSF 的支持下，弗吉尼亚大学的量子光学小组率先在光参量振荡器中实施 QOFC，并实现了多部分纠缠（60 量子模）的创纪录水平。基于集成微谐振器的光学频率梳、异质光子集成和接近单位量子效率的光电二极管多年来一直是 UVA 微光子学、光电和光子器件组的研究重点。该项目旨在将这些努力结合起来，创建一种独特的芯片集成器件，具有多模量子发射器、量子模式处理和检测功能。这种实现使得芯片上的众多量子应用成为可能，包括大规模可扩展的簇纠缠、可扩展的确定性量子处理、QOFC 上的量子秘密共享以及量子模式排序。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
