Measuring the characteristics of quantum materials under high pressure is challenging and laborious. But with the joint efforts of Professor Goh and Professor Yang, the team established that the diamond quantum sensor could perform magnetic detection and microscopic imaging under extreme conditions of low temperature and high pressure. Not only does the breakthrough bring high-pressure superconductivity research onto another level, but also offers a novel and versatile technique to study quantum materials, opening up possibilities of revolutionising the design of quantum materials to benefit society and raising the city’s capability of metrology and high-precision instrumentation.

The findings have also been published in Science.
