Quantum enabled measurements are a way to vastly improve measurement sensitivity in a variety of domains. Magnetic field measurement is a key target for this, since precision measurement of small magnetic fields is a crucial parameter for geophysical exploration, a variety of technological fields, and biophysical measurements. Optically detected magnetic resonance using solid-state diamond crystals containing NV centres is a powerful way to measure small magnetic fields. Measurements can be achieved without the bulky cryogenic cooling apparatus needed for other techniques such as SQUIDS. In this proposal we propose to design, build and demonstrate a quantum magnetometer using diamond NV centres and a novel quantum Berry phase readout protocol. This will be a step toward a compact field-deployable unit with applications in geophysics and other areas. Such a device has the potential to revolutionize magnetic field measurements using the power of quantum mechanical measurements.

量子测量是一种极大提高各个领域测量灵敏度的方法。磁场测量是其中的一个关键目标，因为小磁场的精确测量是地球物理勘探、各种技术领域和生物物理测量的关键参数。使用含有 NV 中心的固态金刚石晶体进行光学检测磁共振是测量小磁场的有效方法。无需 SQUIDS 等其他技术所需的笨重低温冷却设备即可实现测量。在本提案中，我们建议使用金刚石 NV 中心和新颖的量子 Berry 相位读出协议来设计、构建和演示量子磁力计。这将是迈向紧凑型现场部署单元的一步，可应用于地球物理学和其他领域。这种设备有可能利用量子力学测量的力量彻底改变磁场测量。
