Squeezed coherent state
(重定向自Squeezed state)
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
