Multichannel highly sensitive diamond quantum magnetometer
Atsumi Yoshimura, Ayumi Kanamoto, Naota Sekiguchi +9
We demonstrate a highly sensitive real-time magnetometry method at two measurement points. This magnetometry method is based on the frequency-division multiplexing of continuous-wa…

Dispersive measurement of spin shot noise in a Bose--Einstein condensate
Kosuke Shibata, Naota Sekiguchi, Junnosuke Takai +1
We report dispersive spin shot noise measurement of a Bose--Einstein condensate (BEC). While dispersive probing has been used for quantum spin noise measurement of thermal and cold…
