Effect of surface oxidation on electron spin coherence of single nitrogen-vacancy centers in nanodiamonds
Ryuta Tsukahara, Masazumi Fujiwara, Yoshihiko Sera +6
Fluorescent nanodiamonds (NDs) are crystal defect-based light-emitting nanoparticles that can be applied to quantum information science and quantum sensing. Of particular interest…
Observation of rotational Brownian motion of single diamond nanoparticles
Masazumi Fujiwara, Yutaka Shikano, Ryuta Tsukahara +2
Capturing the rotational motion of single nanoparticles has been hindered owing to the difficulty of acquiring directional information under the optical diffraction limit. Here, we…
Monitoring spin coherence of single nitrogen-vacancy centers in nanodiamonds during pH changes in aqueous buffer solutions
Masazumi Fujiwara, Ryuta Tsukahara, Yoshihiko Sera +4
We report on sensing stability of nanodiamond (ND) quantum sensors in various pH aqueous buffer solutions for the two detection schemes of quantum decoherence spectroscopy and ther…
