摘要: In the previous chapter, we have seen that in order to achieve quantum ground state of a mechanical oscillator, with three-mode or even general optomechanical devices, cavity bandwidth needs be smaller than frequency. This is so-called resolved-sideband good-cavity limit. this provide new but physically equivalent insight into origin such limit: information loss due finite bandwidth.
