SIMIS Seminar series on Quantum computing, Quantum simulation and Strongly-correlated systems: Spin Quantum Sensing Technology and Its Advanced Applications

Speaker: Min Jiang (USTC)

Abstract: With the rapid development of quantum precision measurement, particularly in the active control and manipulation of quantum systems, the accuracy of measuring physical quantities such as electromagnetic fields, rotation, time, and gravity has been significantly enhanced. This advancement provides novel methods for frontier scientific endeavors, including material detection and the test of fundamental physical principles. This report first introduces several newly discovered spin effects, such as the spin amplification effect, and the ultra-sensitive magnetic field sensing technology developed from these effects, achieving magnetic field sensitivity surpassing the fT level. Unlike SERF atomic magnetometers, this technology does not require zero magnetic environments, greatly broadening its range of applications. Additionally, the spin system employed in this technology is based on nuclear spin, offering higher energy resolution compared to electron spin sensors. Finally, the report will discuss how spin quantum precision measurement technology can be applied to precise measurements of chemical molecular structures, dark matter searches, and other research areas. In particular, our recent laboratory results surpass the dark matter limits placed based on SN1987A supernovae observation, potentially leading to significant breakthroughs in fundamental science.
