Diamond quantum sensors have been actively studied for applications in biomagnetic field measurements such as brain magnetic fields. Particularly, simultaneous measurement of brain magnetic fields at multiple points on the scalp is necessary for estimating brain activity from brain magnetic fields. In this study, we developed diamond quantum sensors capable of simultaneously measuring magnetic fields at two points with millimeter scaling for simultaneous multi-point detection of a brain magnetic field of a rat. Currently, we work on enhancing sensitivity and developing capabilities for measuring at multiple points to advance practical applications.
