Quantum optical magnetometers (QOM) are quantum magnetic sensors. They are leading candidates for mitigating challenges in magnetic sensing applications such as medical magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) spectroscopy, e.g., for crude oil analysis and pharmaceutical development. Existing QOM have limited sensitivity. This limitation stems from the absence of suitable ultraviolet lasers, necessitating infrared-sensitive agents that degrade performance.We propose a new QOM approach, enabled by novel laser technology that we develop (powerful ultraviolet frequency comb lasers). This room temperature method is expected to greatly exceed state of the art magnetic sensing sensitivity, including that of cryogenic systems. Further improvement is anticipated by implementation of quantum protocols utilizing entanglement, such as spin squeezing.We will develop a prototype of this QOM and carry out proof of principle demonstrations of quantum magnetic sensing. The development process will also serve to train highly qualified personnel in the emerging field of quantum sensing. Furthermore, we will utilize the University of Alberta Technology Transfer Services for invention disclosures and as a liaison to industry partners in Alberta.Anticipated outcomes are enhanced capabilities in real-world settings, cost and footprint reduction, and alleviation of environmental constraints for applications that utilize magnetic sensors. These include medical MRI scanners and NMR spectrometers for oil analysis and pharmaceutical development.Furthermore, revenue would be generated through licensing and/or selling of the proposed technology. Finally, developing the quantum sensing and memory platform proposed here will strengthen Alberta's quantum ecosystem and leadership position in quantum technology.

量子光学磁强计（库姆）是一种量子磁传感器。它们是缓解磁传感应用（如医学磁共振成像（MRI）和核磁共振（NMR）光谱学）挑战的主要候选产品，例如，用于原油分析和药物开发。现有的库姆具有有限的灵敏度。这种限制源于没有合适的紫外激光器，需要红外敏感剂，降低performance.We提出了一种新的库姆光学方法，使我们开发的新的激光技术（强大的紫外频率梳状激光器）。这种室温方法有望大大超过现有技术的磁感应灵敏度，包括低温系统的灵敏度。进一步的改进是通过实现利用纠缠的量子协议，如自旋压缩。我们将开发这种库姆模型的原型，并进行量子磁传感的原理证明演示。开发过程还将有助于培养新兴量子传感领域的高素质人才。此外，我们将利用阿尔伯塔大学技术转移服务进行发明披露，并作为与阿尔伯塔行业合作伙伴的联络人。预期结果是增强现实环境中的能力，降低成本和占地面积，并减轻利用磁传感器的应用的环境限制。其中包括用于石油分析和药物开发的医用核磁共振扫描仪和核磁共振光谱仪。此外，通过许可和/或出售拟议技术将产生收入。最后，开发这里提出的量子传感和存储平台将加强阿尔伯塔的量子生态系统和量子技术的领导地位。
