Systematic characterization of nanoscale -BN quantum sensor spots created by helium-ion microscopy
Hao Gu, Moeta Tsukamoto, Yuki Nakamura +8
The nanosized boron vacancy () defect spot in hexagonal boron nitride (-BN) is promising for a local magnetic field quantum sensor. One of its advantages is that…
Observation of chiral domain walls in an octupole-ordered antiferromagnet
Moeta Tsukamoto, Zhewen Xu, Tomoya Higo +10
Spin chirality in antiferromagnets offers new opportunities for spintronics. The kagome antiferromagnet Mn3Sn is a paradigmatic material in which the antiferromagnetic order parame…
Heron-Bench: A Benchmark for Evaluating Vision Language Models in Japanese
Yuichi Inoue, Kento Sasaki, Yuma Ochi +3
Vision Language Models (VLMs) have undergone a rapid evolution, giving rise to significant advancements in the realm of multimodal understanding tasks. However, the majority of the…
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…
Polarization- and frequency-tunable microwave circuit for selective excitation of nitrogen-vacancy spins in diamond
Johannes Herrmann, Marc A. Appleton, Kento Sasaki +4
We report on a planar microwave resonator providing arbitrarily polarized oscillating magnetic fields that enable selective excitation of the electronic spins of nitrogen-vacancy (…
