Abstract
We show that the detection sensitivity of a linear detector is lower bounded by some quantum limits. For the force detection, relevant for atomic force microscopes, the lower bound is given by the so-called ultimate quantum limit. For the displacement detection, relevant for detecting gravitational waves, a generalized lower bound is obtained.
