RAISE: TAQS: On-Chip Entanglement, Preparation, Manipulation, and Detection for Integrated All Quantum Information Processing

在过去的60年里，人类的计算能力取得了前所未有的进步，实现了以前无法想象的应用。这是随着电子集成电路的出现而实现的，在电子集成电路中，数十亿个电子元件被构建在单个芯片上。由于最近光子集成电路的商业化，人类交换信息的能力也经历了类似的范式转变，光子集成电路是电子集成电路的光学模拟，它对光而不是电进行信息编码。新兴的量子信息处理领域，利用电子和/或光子的量子力学特性来编码和处理信息，为更安全、更节能的通信和计算提供了潜力。不幸的是，目前还没有现成的材料工具包可以在单个集成电路芯片上执行所有必要的量子信息处理功能。该项目的目标是展示这样一个材料平台，并利用它对光的关键量子特性进行基本的科学测量。研究成果将通过重要的课程开发与教育相结合，提供广泛可访问的跨学科量子信息课程，这对劳动力培训至关重要。通用线性光学量子信息处理的基本资源是在芯片上创建和表征贝尔态的能力，该贝尔态可以扩展到簇态。这是量子计算、量子密码学和量子网络（量子互联网的节点）的关键构建块。光子集成电路已经彻底改变了现代光纤通信系统，但无法满足未来量子信息系统的需求。该奖项支持一项雄心勃勃的努力，即创建一个可扩展的光子集成电路平台，用于电信波长的量子信息处理，并利用它来生成和操纵芯片上的贝尔态。该项目将利用基于磷化铟（InP）芯片的现有技术基础设施，这是长距离光子集成电路的主要平台。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。

The past six decades have witnessed unprecedented progress in humanity's ability to compute, enabling applications that were previously unimaginable. This has been achieved with the advent of the electronic integrated circuit, where billions of electrical elements are built together on a single chip. Humanity's ability to exchange information has undergone a similar paradigm shift, due to the recent commercialization of the photonic integrated circuit, the optical analog of the electronic integrated circuit, which encodes information on light, rather than electricity. The emerging field of quantum information processing, where quantum mechanical properties of electrons and/or photons are used to encode and process information, offers the potential for more secure and energy-efficient communications and computation. Unfortunately, there is no established toolkit of materials that can perform all of the necessary quantum information processing functions on a single integrated circuit chip. The goal of this project is to demonstrate such a materials platform and to harness it to perform fundamental scientific measurements of key quantum properties of light. Research results will be integrated with education through important curricular development by offering a broadly accessible, interdisciplinary course on quantum information that is essential for workforce training.A fundamental resource for universal linear optical quantum information processing is the ability to create and characterize Bell states on a chip that can be extended to cluster states. This is a key building block for quantum computing, quantum cryptography, and quantum networks (nodes of the Quantum Internet). Photonic integrated circuits have revolutionized modern optical fiber communication systems, but are unable to address the needs of future quantum information systems. This award supports an ambitious effort to create a scalable photonic integrated circuit platform for quantum information processing at telecommunications wavelengths and employ it to generate and manipulate Bell states on-chip. This project will leverage the existing technology infrastructure of Indium Phosphide (InP)-based chips, the dominant platform for long-haul photonic integrated circuits.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.
