The NSF Convergence Accelerator program supports use-inspired, team-based, multidisciplinary efforts that address challenges of national importance and will produce deliverables of value to society in the near future. Current high-precision inertial sensors are bulky and prohibitive, holding back a wide impact, e.g., for self-driving cars, wearable healthcare devices, and secure navigation in GPS-denied environment.The goal of this project is to develop the functional inertial sensing modules and control units and converge on a fully integrated quantum-enhanced inertial measurement unit (QEIMU) prototype as the end- of-project deliverable. The intellectual merit of this project is in developing a multilayer silicon nitride platform on which team members will fabricate and assemble quantum-light sources, gyroscopes, and accelerometers.The QEIMU prototype will improve key performance metrics for gyroscopes and accelerometers, including the angle random walk (ARW), sensitivity, and bias by one-to-two orders of magnitude and, at the same time, enjoy low cost, compactness, a clear pathway to mass productivity, and robustness. Such unique features will make the QEIMU widely and readily available for the commercial markets of self-driving cars, aerospace navigation, and handheld sensing devices as well as space and defense-oriented applications, thereby creating near-term and profound societal impacts within 5-10 years.The QEIMU module is envisaged to be installed on 1) autonomous vehicles for secure navigation without GPS signals; 2) mobile devices as a complementary precise indoor positioning technique; and 3) activity recognition systems for medical diagnostics, home monitoring, assisted living, and sport-related applications. The broader impact of this project will be on inertial sensors market and their adoption in many markets that are currently untapped. The impact will also be on engagement and education of underrepresented groups in quantum technology. "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.

NSF 融合加速器计划支持以使用为基础的、基于团队的、多学科的努力，以应对具有国家重要性的挑战，并将在不久的将来为社会提供有价值的成果。目前的高精度惯性传感器体积庞大且令人望而却步，无法产生广泛的影响，例如，对于自动驾驶汽车、可穿戴医疗设备以及 GPS 拒绝环境中的安全导航。该项目的目标是开发功能性惯性传感模块和控制单元，并汇聚成完全集成的量子增强惯性测量单元（QEIMU）原型作为项目结束时的交付成果。该项目的智力优势在于开发了一个多层氮化硅平台，团队成员将在该平台上制造和组装量子光源、陀螺仪和加速计。QEIMU 原型将改善陀螺仪和加速计的关键性能指标，包括角度随机游走(ARW)、灵敏度和偏差提高一到两个数量级，同时具有低成本、紧凑性、实现大规模生产的清晰途径和鲁棒性。这些独特的功能将使 QEIMU 能够广泛、方便地应用于自动驾驶汽车、航空航天导航、手持传感设备以及空间和国防应用的商业市场，从而在 5 年内产生短期和深远的社会影响。 10年。QEIMU模块预计安装在1）自动驾驶车辆上，在没有GPS信号的情况下进行安全导航； 2）移动设备作为补充精确室内定位技术； 3) 用于医疗诊断、家庭监控、辅助生活和运动相关应用的活动识别系统。该项目的更广泛影响将是对惯性传感器市场及其在许多目前尚未开发的市场的采用。这还将影响量子技术领域代表性不足的群体的参与和教育。 “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进行评估，被认为值得支持。
