Robust Diamond Quantum Sensing in Double-Quantum 4-Ramsey Interferometry by Dual-Feedback Scheme
Yuta Araki, Takeharu Sekiguchi, Yuji Hatano +11
We developed a highly sensitive and long-term stable diamond quantum magnetometer by integrating a dual-feedback system that compensates for common- and differential-mode frequency…
Efficient creation of shallow NV ensembles by high-angle ion implantation
Kento Sasaki, Hideyuki Watanabe, Tokuyuki Teraji +3
Negatively charged nitrogen-vacancy (NV) centers located a few nanometers below the diamond surface are key quantum defects for nanoscale sensing of external spins. However, th…
A Highly Sensitive Diamond NV Magnetometer Using Ramsey Interferometry with a Short Sensor-to-Sample Distance
Yuta Araki, Takeharu Sekiguchi, Yuji Hatano +11
In this study, we developed a diamond quantum magnetometer based on Ramsey interferometry with a short sensor-to-sample distance. Conventional biomagnetic sensors with ensemble nit…
