本课题组和国家电网合作,正在开发电力市场应用的电流传感器。在新能源产业的发展下,电力行业电网系统等对电流传感器的需求越来越大,为此,开发用于电网大电流监测的量子电流传感器,服务于未来智能电网智能调度的需求。
超极化核自旋量子电流传感器是一种新型电流测量传感器,当前并未看到将其应用于电网大电流测量的相关研究报道,本项目的实施将有望在电网大电流测量方面进行原始创新。超极化核自旋量子电流传感器使用核自旋进行磁场测量,由于核自旋的旋磁比是电子自旋的千分之一且基于3He核自旋,其相干时间远远大于电子自旋,可以预见,基于3He核自旋可以对磁场进行更高精度的测量。
Chip-scale atomic magnetometer for state grid market:
Our research group, in collaboration with the State Grid Corporation of China, is currently developing a current sensor for applications in the power market. With the growing demand for current sensors in the power industry and grid systems due to the development of renewable energy, there is a need for quantum current sensors designed for large current monitoring in power grids. This aims to cater to the future requirements of intelligent grid management.
The hyperpolarized nuclear spin quantum current sensor is a novel current measurement sensor. Currently, there is no reported research on its application in large current measurements for power grids. The implementation of this project is expected to bring about original innovations in the field of large current measurements for power grids. The hyperpolarized nuclear spin quantum current sensor utilizes nuclear spin for magnetic field measurements. Due to the fact that the gyromagnetic ratio of nuclear spin is one-thousandth of that of electron spin and is based on 3He nuclear spin, its coherence time is much longer than that of electron spin. It is foreseeable that based on 3He nuclear spin, higher precision measurements of magnetic fields can be achieved.

Chip scale atomic spin gyroscope:
The atomic gyroscope utilizes the characteristic of atomic spin to maintain a fixed axis in inertial space for measuring angular velocity. It exhibits super high sensitivity in measuring rotational angular velocity. Combining atomic gyroscope sensors with chip technology is expected to overcome the size limitations of current sensors and reduce sensor costs. This has the potential for widespread applications in areas such as autonomous driving, unmanned aerial vehicles (drones), and unmanned submersibles.
