Spin-coherence characterization of boron vacancy defects in hexagonal boron nitride with broadband microwave pulses
Yuki Nakamura, Takuya Iwasaki, Shu Nakaharai +6
Negatively charged boron vacancy (VB-) defects in hexagonal boron nitride (hBN) are promising for nanoscale-proximity quantum sensing. To evaluate their performance, it is importan…
Beyond ensemble averaging: Parallelized single-shot readout of hole capture in diamond
Richard Monge, Yuki Nakamura, Olaf Bach +7
Understanding the generation, transport and capture of charge carriers in semiconductors is of fundamental technological importance. However, the ensemble measurement techniques ub…
Systematic investigation of dynamic nuclear polarization with boron vacancy in hexagonal boron nitride
Yuki Nakamura, Shunsuke Nishimura, Takuya Iwasaki +7
Dynamic nuclear polarization (DNP) using the boron vacancy () in hexagonal boron nitride (hBN) has gained increasing attention. Understanding this DNP requires syst…
Surface criticality in the mixed-field Ising model with sign-inverted next-nearest-neighbor interaction
Yuki Nakamura, Ryui Kaneko, Ippei Danshita
Rydberg atoms in an optical tweezer array have been used as a quantum simulator of the spin- antiferromagnetic Ising model with longitudinal and transverse fields. We suggest…
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…
