In physics, a squeezed coherent state is any state of the quantum mechanical Hilbert space such that the uncertainty principle is saturated. That is, the product of the corresponding two operators takes on its minimum value:
The simplest such state is the ground state of the quantum harmonic oscillator. The next simple class of states that satisfies this identity are the family of coherent states .
Often, the term squeezed state is used for any such state with in "natural oscillator units". The idea behind this is that the circle denoting a coherent state in a quadrature diagram (see below) has been "squeezed" to an ellipse of the same area.

Famous quotes containing the words squeezed, coherent and/or state:
“Modern women are squeezed between the devil and the deep blue sea, and there are no lifeboats out there in the form of public policies designed to help these women combine their roles as mothers and as workers.”
—Sylvia Ann Hewitt (20th century)
“We have good reason to believe that memories of early childhood do not persist in consciousness because of the absence or fragmentary character of language covering this period. Words serve as fixatives for mental images. . . . Even at the end of the second year of life when word tags exist for a number of objects in the child’s life, these words are discrete and do not yet bind together the parts of an experience or organize them in a way that can produce a coherent memory.”
—Selma H. Fraiberg (20th century)
“The state is therefore everyone; the rules within the state are laws which safeguard the welfare of all and which must originate from the welfare of all.”
—Georg Büchner (1813–1837)
