Diamond quantum-sensing platform with integrated boron-doped diamond microwave antenna and thermometer
Masahiro Ohkuma, Ryo Matsumoto, Shintaro Adachi +5
Wide-field nitrogen-vacancy (NV) magnetic imaging at cryogenic temperatures requires microwave excitation and reliable knowledge of the temperature near the sensing region. Here, w…
Wide-field NV magnetometry under simultaneous high-pressure and high-temperature conditions
Masahiro Ohkuma, Eikichi Kimura, Shumpei Ohyama +7
We demonstrate wide-field optically detected magnetic resonance (ODMR) under simultaneous high-pressure and high-temperature conditions using nitrogen-vacancy (NV) centers. Althoug…
Coherent control of solid-state defect spins via patterned boron-doped diamond circuit
Masahiro Ohkuma, Eikichi Kimura, Eunsang Lee +8
Monolithic integration, which refers to the incorporation of all device functionalities within a single material, shows significant potential for creating scalable solid-state quan…
