Abstract

Section titled ā€œAbstractā€

Abstract Nitrogen-vacancy (NV) quantum defects in diamond are sensitive detectors of magnetic fields. Then, the existing sensing technologies based on diamond NV centers rely on bulky and expensive instruments, which must be replaced by a more compact design. Here we combine NV quantum sensing technology with integrated circuit technology to create a compact and easy-to-operate platform. Using the existing integrated circuit technology, we integrate the lock-in amplifier, microwave generator and TTL modulator together. with this platform, we can obtain a magnetic sensitivity of 5.72Ī¼T/Hz 1/2 .
