Demonstration of highly-sensitive wideband microwave sensing using ensemble nitrogen-vacancy centers
Kensuke Ogawa, Shunsuke Nishimura, Kento Sasaki +1
Microwave magnetometry is essential for the advancement of microwave technologies. We demonstrate a broadband microwave sensing protocol using the AC Zeeman effect with ensemble ni…
Suppression of Pulsed Dynamic Nuclear Polarization by Many-Body Spin Dynamics
Kento Sasaki, Eisuke Abe
We study a mechanism by which nuclear hyperpolarization due to the polarization transfer from a microwave-pulse-controlled electron spin is suppressed. From analytical and numerica…
Nitrogen isotope effects on boron vacancy quantum sensors in hexagonal boron nitride
Kento Sasaki, Takashi Taniguchi, Kensuke Kobayashi
There has been growing interest in studying hexagonal boron nitride (hBN) for quantum technologies. Here, we investigate nitrogen isotope effects on boron vacancy (V) de…
Demonstration of geometric diabatic control of quantum states
Kento Sasaki, Yuki Nakamura, Tokuyuki Teraji +2
Geometric effects can play a pivotal role in streamlining quantum manipulation. We demonstrate a geometric diabatic control, that is, perfect tunneling between spin states in a dia…
Frequency-tunable magnetic field sensing using continuous-wave optically detected magnetic resonance with nitrogen-vacancy centers in diamond
Ryusei Okaniwa, Takumi Mikawa, Yuichiro Matsuzaki +8
The nitrogen-vacancy (NV) center is a promising candidate to realize practical quantum sensors with high sensitivity and high spatial resolution, even at room temperature and atmos…
