Quantum Current Sensor for Power Grid Applications

In close collaboration with the State Grid Corporation of China, our group is dedicated to the research and development of quantum current sensors for ultra-high voltage power grids. This initiative addresses the urgent need for high-precision, all-optical current sensing in power systems, driven by the rapid growth of the new energy industry. Our goal is to develop quantum current sensors that enable precise monitoring of large currents in power grids, supporting the intelligent dispatching requirements of future smart grids.

Currently, we employ Doppler-free saturated absorption spectroscopy for measurements, representing an innovative all-optical sensing approach. By converting atomic absorption line frequencies into magnetic field measurements, we achieve non-contact, high-precision measurement of grid currents. This method overcomes the limitations of traditional current transformers, offering significant advantages such as high insulation, strong anti-interference capabilities, and a wide dynamic range, making it particularly suitable for complex ultra-high voltage power grid environments.

Our research areas include:

• Chip integration and miniaturization of atomic magnetometers: Integrating core components of quantum sensors at the chip level for miniaturization and cost reduction.
• Design and optimization of all-optical measurement systems: Developing and optimizing measurement systems based on Doppler-free saturated absorption spectroscopy.
• Quantum current sensing technology in complex electromagnetic environments: Addressing electromagnetic interference in power grid sites to ensure measurement accuracy.
• On-site testing and application in collaboration with the State Grid: Translating laboratory achievements into practical power grid operations.

This project demonstrates significant original innovation through the interdisciplinary integration of quantum physics, atomic spectroscopy, optical engineering, circuit design, and power system applications. Specifically, converting atomic absorption line frequencies into magnetic field measurements to realize all-optical power grid current measurement provides an unprecedented solution for the power industry. Joining our team offers the opportunity to:

• Master skills in quantum sensing, precision optical measurement and advanced circuit design.
• Participate in major scientific research projects with the State Grid, applying cutting-edge physics to national energy strategies.
• Gain rich engineering practice experience, laying a solid foundation for future employment in high-tech fields such as quantum technology and power energy.
