Squeezed states of light

In quantum physics, light is in a squeezed state if its electric field strength Ԑ for some phases ϑ {\displaystyle \vartheta } has a quantum uncertainty smaller than that of a coherent state. The term squeezing thus refers to a reduced quantum uncertainty. To obey Heisenberg's uncertainty relation, a squeezed state must also have phases at which the…
