Unbiased Estimation of Conditional Covariance for Quantum Optomechanics
Katsuta Sakai, Nobuyuki Matsumoto
Continuous measurements can prepare macroscopic mechanical oscillators in conditional quantum states, but their covariance is difficult to verify. The conventional retrodictive est…

Towards a spatial cat state of a massive pendulum
Satoshi Iso, Jinyang Li, Nobuyuki Matsumoto +1
We propose an experiment for constructing a spatial cat state of a suspended mirror with an order of (mg). The mirror is set at the center of two mirrors, creating two…
