项目摘要

Title: A semiconductor-diamond nanophotonic transmitter for long-distance quantum communication Nontechnical description: Quantum communication is fundamentally secure. Currently, quantum-secure communication distance is limited to less than 100 km by photon absorption in fibers. Theoretically, this limitation can be overcome by a network of quantum repeaters relying on entanglement between communication nodes. The experimental quantum communication community has primarily focused on higher performance metrics for a single device. As a result, proof-of-principle experiments illustrating the potential of quantum technologies for secure communication have been realized utilizing physically large, expensive, and non-scalable technologies at cryogenic temperatures. The critical question remains whether long-distance communication, utilizing quantum repeaters, can be realized in a scalable platform. To reach this goal, this work employs two transformative approaches. First, an integrated hybrid-materials platform that has the potential to realize all device functionalities required for a quantum transmitter is adopted. Second, state-of-the-art computational techniques are utilized to design photonic devices that exhibit unprecedented nonlinear capabilities, enabling the desired performance under the constraints of compatibility with semiconductor fabrication processing. In particular, compact devices are designed to efficiently extract photons emitted by a defect in diamond; the extracted photons are then routed into a nonlinear device that efficiently converts them to telecom wavelengths; finally, the photons are coupled into an optical fiber for low-loss, long-distance propagation. The technologies engineered to reach this goal are expected to also advance the current state of optical information processing and sensing, due to improved nonlinear optical and reconfigurable devices. The diverse team of investigators will train the next generation of photonics engineers in skills including nanophotonic design, nanofabrication, optical spectroscopy, and integrated quantum technologies for tomorrow's optoelectronics industry. Recruitment at all levels, from pre-college to postdoctoral, will have a focus on broadening participation to further integrate women, underrepresented minorities and veterans through direct integration into the scientific team as well as outreach efforts including a proposed EFRI-REM residential program and Science Cafés to engage the investigators? local communities in the fields of optical and quantum communication.Technical description: This proposal seeks to realize a photonic integrated circuit for creating and transmitting indistinguishable spin-entangled photons at telecom wavelength. Emission of spin-entangled photons from diamond color centers will be enhanced by a waveguide-coupled resonant plasmonic device, providing an avenue toward operation at elevated temperature. These photons will be spectrally filtered and dynamically routed via an optical switching network to an integrated quantum frequency converter. The resulting telecom-wavelength single photons will be further filtered before off-chip coupling to a fiber-optic cable. The design of the resonant enhancement and nonlinear frequency conversion devices will be performed by a novel inverse-design method based on topology optimization that has only recently become tractable with available computation resources. Several key avenues are identified to mitigate against unavoidable device inhomogeneities and enhance the prospects for scalability. Nonlinear frequency conversion will simultaneously perform frequency conversion and spectral which-path erasure necessary for quantum entanglement. Tunable ring resonators simultaneously provide filtering and routing capabilities. In the short-term, realization of the quantum communication transmitter will require unprecedented integration of quantum optics, nanophotonics, plasmonics, and nonlinear optics. In the long-term, the proposed technology has the potential to enable long-distance, fiber-based, unconditionally secure communication.

标题：长距离量子通信非技术描述：量子通信从根本上安全。当前，量子安全通信距离限制为纤维中的光子抽象小于100 km。理论上，这种限制可以通过依靠通信节点之间纠缠的量子中继器网络来克服。实验量子通信社区主要集中于单个设备的高性能指标。结果，原理证明实验说明了量子技术对安全通信的潜力已通过低温温度下的物理大型，昂贵且不可缩放的技术实现。关键的问题是，是否可以在可扩展的平台中实现长距离通信（使用量子中继器）。为了实现这一目标，这项工作员工两种变革性的方法。首先，采用量子发射器所需的所有设备功能的综合混合物质平台。其次，最新的计算技术用于设计裸露前所未有的非线性功能的光子设备，从而在与半导体制造处理的兼容性约束下实现了所需的性能。特别是，紧凑的设备旨在有效提取钻石缺陷发出的照片；然后将提取的照片路由到非线性设备中，从而有效地将其转换为电信波长。最后，将照片耦合到光纤中，以进行低损失，长距离传播。由于改进的非线性光学和可重新配置的设备，预计旨在实现此目标的技术也将推动光学信息处理和传感的当前状态。研究人员的潜水团队将培训下一代光子工程师。在明天的光电行业的纳米光设计，纳米制作，光谱和综合量子技术等技能上。从大学前到博士后的各个层面的招聘将着重于扩大参与，通过直接整合到科学团队中，进一步融合了妇女，代表性不足的少数群体和退伍军人，以及推出工作，以及拟议的EFRI-REM居民计划和科学咖啡馆，以吸引研究人员参与研究人员？光学和量子通信领域的当地社区。技术描述：该提案旨在实现一个光子整合电路，用于在电信波长处创建和传输无法区分的旋转式照片。通过波导耦合的谐振浆液设备，将增强钻石颜色中心的自旋式照片的排放，从而为在升高温度下运行提供了途径。这些照片将通过光谱过滤，并通过光学开关网络动态路由到集成的量子转换器。在将芯片耦合到光纤电缆之前，将产生的电信波长单照片将进一步过滤。谐振增强和非线性频率转换设备的设计将通过基于拓扑优化的新型逆设计方法执行，该方法直到最近才可以使用可用的计算资源来处理。确定了几种关键途径，以减轻不可避免的设备不均匀性并增强可伸缩性的前景。非线性频率转换将简单地执行频率转换和频谱，量子纠缠所必需的删除。可调环谐振器只需提供过滤和路由功能即可。在短期内，量子通信发射器的实现将需要量子光学，纳米光子学，等离子体和非线性光学的空前整合。从长远来看，提出的技术有可能使长距离，基于纤维的，无条件安全的通信。
