Quantum information processing opens new avenues for next-generation high-precision sensing, high-performance computing, and reliable communications. Entanglement is a unique resource for quantum information processing. Quantum communication is the cornerstone to fully unleash the power of entanglement. On the secure communication front, quantum communication leverages underlying principles of quantum mechanics to realize distribution of keys with verifiable security, known as Quantum Key distribution (QKD). Despite appealing features of quantum communication, a number of fundamental and technical challenges need to be tackled prior to its widespread applications. This project will develop high-dimensional protocols and tailored efficient photonic-integrated circuits to substantially advance scalable, high-rate, and long-haul quantum communications, thus providing solutions to challenges faced in practical deployments. This work enables high spectral efficiency quantum communications so that communication rates can be substantially improved. As such, this project will represent an essential step toward low-cost integrated quantum communication systems that can be mass-produced.High-dimensional quantum communication enables transmitting quantum information in a large Hilbert space, opening promising routes for constructing new quantum error-correcting codes, building efficient quantum repeaters, and high-rate quantum-secured communications. The project seeks to introduce a new framework of quantum communications with high-dimensional entangled-qubits encoded in orthogonal Slepian sequences bases. This approach is highly robust against turbulence effects in free-space optical links and dispersion effects/nonlinearities in fiber-optics channels, thereby improving the quantum communication distance. Generation, processing, and detection of Slepian-states will be implemented in an integrated quantum photonics platform. This project will make possible the development of electronically controlled waveguide Bragg gratings (EC-WBGs) implemented in nonlinear photonic-integrated circuits as a key component employed in the quantum transmitters and receivers for high-dimensional quantum communications. Compared to fiber Bragg gratings, EC-WBGs can be mass fabricated in a photonic-integrated circuit platform, so that quantum information encoded in a large number of mutually unbiased basis can be processed. As such, scalability is significantly improved while substantially reducing the cost. The Slepian-state sources and the photonic-integrated circuits-based EC-WBGs will be integrated to perform quantum communication tasks including high-dimensional entanglement distribution and high-dimensional QKD. This project is dedicated to 1) analyzing high-dimensional quantum communication protocols based on Slepian states; 2) developing entangled and single-photon-level Slepian-state sources and scalable processing units in a photonic-integrated circuit platform; and 3) demonstrating Slepian-state high-dimensional quantum communication systems and testing the developed high-dimensional quantum communication prototypes in a real-world quantum network testbed.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.

量子信息处理为下一代高精度传感，高性能计算和可靠的通信开辟了新的途径。纠缠是量子信息处理的独特资源。量子通信是完全释放纠缠力量的基石。在安全的通信方面，量子通信利用了量子力学的基本原理，以实现具有可验证安全性的密钥分布，称为量子密钥分布（QKD）。尽管量子通信具有吸引人的特征，但在广泛应用之前仍需要解决许多基本和技术挑战。该项目将开发高维协议和量身定制的有效的光子集成电路，以实质上提高可扩展，高率和长途量子通信，从而为实践部署中面临的挑战提供解决方案。这项工作使高光谱效率量子通信能够大大提高通信率。因此，该项目将代表朝着可以大规模生产的低成本集成量子通信系统迈出的重要步骤。高维量子通信可以在大希尔伯特空间中传输量子信息，开辟了有希望的途径，用于构建新的量子错误纠正范围，构建新的量子错误校正代码，构建有效的量子折扣和高速量化量子量化的通信。该项目旨在通过在正交SLEPIAN序列底座中编码的高维纠缠量的量子通信框架引入新的量子通信框架。这种方法在自由空间的光学连接和色散效应/非线性中的湍流效应非常强大，从而改善了量子通信距离。 SLEPIAN状态的生成，处理和检测将在集成的量子光子平台中实施。该项目将使在非线性光子集成电路中实现的电子控制的波导Bragg Graggs（EC-WBG）的发展成为可能，作为用于高维量子通信的量子发射器和接收器中使用的关键组件。与纤维bragg光栅相比，可以在光子集成电路平台中制造EC-WBG，因此可以处理以大量相互无偏的基础编码的量子信息。因此，可伸缩性大大提高，同时大大降低了成本。 SLEPIAN状态的来源和基于光子的电路EC-WBG将集成以执行量子通信任务，包括高维纠缠分布和高维QKD。该项目致力于1）分析基于SLEPIAN状态的高维量子通信协议； 2）在光子集成电路平台中开发纠缠和单级级别的SLEPIAN状态源和可扩展的处理单元； 3）在现实世界中量子网络测试床中展示SLEPIAN-StATE高维量子通信系统，并测试开发的高维量子通信原型。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优点和更广泛影响的评估审查审查标准来通过评估来通过评估来获得支持的。
