For example, the commutator of the creation and annihilation operators that are associated with the same boson state equals one, while all other commutators vanish. Using the method of intertwining operators, commutation relations are rigorously obtained for the creation–annihilation operators associated with the quantum nonlinear Schrödinger equation. The theory of creation/annihilation operators yields a powerful tool for calculating thermodynamic averages of ^q- and ^p-dependent observables, like, ^q2, ^p2, ^q4, ^p4, etc. (Note that from the properties of creation and annihilation operators it is easily seen that the thermal averages of odd powers of q^ and ^pare zero.) The mathematics for the creation and annihilation operators for bosons is the same as for the ladder operators of the quantum harmonic oscillator. For example, the commutator of the creation and annihilation operators that are associated with the same boson state equals one, while all other commutators vanish. Here shows that the state has been removed from the mani-particle state.

And as you will see, the harmonic oscillator spectrum and the properties of the wave functions will follow just from an analysis of these creation/annihilation operators and their commutation relations.
