Time-of-flight force sensing below the quantum zero-point fluctuation
Sotatsu Otabe, Mitsuyoshi Kamba, Yuto Kojima +1
Sensing weak forces through observing a mechanical motion near or below its quantum zero-point fluctuation has been desired in diverse areas. While mechanical oscillators have play…

A levitated nano-accelerometer sensitized by quantum quench
M. Kamba, S. Otabe, K. Funo +2
We realize a nanoscale accelerometer exploiting the nonequilibrium dynamics of a nanoparticle near the quantum ground state. We explore the dynamics after quenching the trapping po…
