Squeezed State and Bogoliubov transformation

What's Squeezed State§

Squeezed state is incredibly useful when it comes down to measurement as we have seen in the last article that it's uncertainty can pulse and periodically damp under the vacuum uncertainty. Thus timing up to the pusling, we can take detection more precisely. Thus, easily, the definition of squeezed state is that it's uncertainty are able to be damped under the vacuum uncertainty.
