Fundamental bound on Wigner negativity generation from environmental collisions
Isaac Layton, Takahiro Sagawa, Ken Funo
Beyond quadratic potentials, classical evolution laws are typically thought to arise from quantum theory as an approximate description. Here we show that classical evolution laws c…

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…
