Trivial examples, which are in fact not squeezed, are the ground state formula_7 of the quantum harmonic oscillator and the family of coherent states formula_8. These states saturate the uncertainty above and have a symmetric distribution of the operator uncertainties with formula_9 in "natural oscillator units" and formula_10. (In literature different normalizations for the quadrature amplitudes are used. Here we use the normalization for which the sum of the ground state variances of the quadrature amplitudes directly provide the zero point quantum number formula_11).
