△ [23p-A202-13] Verification of spin bath driving towards miniaturized and highly sensitive quantum sensor
Keywords:NV center, magnetic sensors, spin manipulation
NV centers in diamond act as highly sensitive magnetic sensors. Miniaturization and increasing magnetic sensitivity of NV centers will enable advanced biological applications. One measurement technique that achieves compactness and high sensitivity is the continuous excitation (CE) Ramsey method. However the magnetic sensitivity is limited by the effect of P1 spin bath. We aimed to implement a high-sensitivity measurement protocol combining the CE-Ramsey with P1 decoupling and verified the effect of spin bath driving.
