Precise measurements of the displacement of, and force acting on, a mechanical oscillator can be performed by coupling the oscillator to an optical cavity. Brownian thermal forces represent a fundamental limit to measurement sensitivity which impe...
We investigated the quantum state of an optomechanical suspended mirror under
continuous measurement and feedback control using Wiener filtering. We focus on
the impact of the two-mode theory of suspended mirror on the quantum state,
which is desc...
Pendulums have long been used as force sensors due to their ultimately low
dissipation (high-quality factor) characteristic. They are widely used in the
measurement of the gravitational constant, detection of gravitational waves,
and determination...
This study is aimed at investigating the feasibility of generating quantum
entanglement between macroscopic mechanical mirrors in optomechanical systems
while under continuous measurement and feedback control. We carefully derive a
covariance matr...

In quantum mechanics, measurement can be used to prepare a quantum state.
This principle is applicable even for macroscopic objects, which may enable us
to see classical-quantum transition. Here, we demonstrate conditional
mechanical squeezing of ...
