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…
Enhanced Emission and Two-Photon Interference of Lead-Vacancy Centers in Diamond Solid Immersion Lenses
Koyo Hirai, Eiki Ota, Yiyang Chen +8
A negatively charged lead-vacancy (PbV-) center in diamond is a novel quantum system which can be operated at a high temperature above 4 K owing to its large ground state splitting…
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…
Multichannel highly sensitive diamond quantum magnetometer
Atsumi Yoshimura, Ayumi Kanamoto, Naota Sekiguchi +9
We demonstrate a highly sensitive real-time magnetometry method at two measurement points. This magnetometry method is based on the frequency-division multiplexing of continuous-wa…
Narrow Inhomogeneous Distribution and Charge State Stabilization of Lead-Vacancy Centers in Diamond
Ryotaro Abe, Peng Wang, Takashi Taniguchi +4
Lead-vacancy (PbV) centers in diamond with a large ground state splitting are expected to be a building block of quantum network nodes. Due to the heaviness of the Pb atom, it is c…
