Fast coherent control of nitrogen-14 spins associated with nitrogen-vacancy centers in diamonds using dynamical decoupling
Kosuke Mizuno, Ikuya Fujisaki, Hiroyoshi Tomioka +5
A nitrogen-vacancy (NV) center in a diamond enables the access to an electron spin, which is expected to present highly sensitive quantum sensors. Although exploiting a nitrogen nu…
Label-free phase change detection of lipid bilayers using nanoscale diamond magnetometry
Hitoshi Ishiwata, Hiroshi C. Watanabe, Shinya Hanashima +2
The NV center in a diamond is a quantum sensor with exceptional quality for highly sensitive nanoscale analysis of NMR spectra and thermometry. In this study, we investigate nanosc…
Simultaneous Wide-field Imaging of Phase and Magnitude of AC Magnetic Signal Using Diamond Quantum Magnetometry
Kosuke Mizuno, Hitoshi Ishiwata, Yuta Masuyama +2
Spectroscopic analysis of AC magnetic signal using diamond quantum magnetometry is a promising technique for inductive imaging. Conventional dynamic decoupling like XY8 provides a…
Wide-field diamond magnetometry with millihertz frequency resolution and nanotesla sensitivity
Kosuke Mizuno, Makoto Nakajima, Hitoshi Ishiwata +3
The nitrogen-vacancy (NV) center in diamond allows room-temperature wide-field quantum magnetometry and metrology for a small volume, which is an important technology for applicati…
Highly sensitive macro-scale diamond magnetometer operated by dynamical decoupling sequence with coplanar waveguide resonator
Yuta Masuyama, Kousuke Mizuno, Hayato Ozawa +5
Ultimate sensitivity for quantum magnetometry using nitrogen-vacancy (NV) centers in diamond is limited by number of NV centers and coherence time. Microwave irradiation with a hig…
Perfectly Aligned Shallow Ensemble Nitrogen-Vacancy Centers in (111) Diamond
Hitoshi Ishiwata, Makoto Nakajima, Kosuke Tahara +3
We report the formation of perfectly aligned, high-density, shallow nitrogen vacancy (NV) centers on the () surface of a diamond. The study involved step-flow growth with a hi…
Nanodiamond integration with photonic devices
Marina Radulaski, Jingyuan Linda Zhang, Yan-Kai Tzeng +13
We discuss the progress in integration of nanodiamonds with photonic devices for quantum optics applications. Experimental results in GaP, SiO2 and SiC-nanodiamond platforms show t…
Hybrid Group IV Nanophotonic Structures Incorporating Diamond Silicon-Vacancy Color Centers
Jingyuan Linda Zhang, Hitoshi Ishiwata, Thomas M. Babinec +13
We demonstrate a new approach for engineering group IV semiconductor-based quantum photonic structures containing negatively charged silicon-vacancy (SiV) color centers in diam…
