Abstract
It is shown that the quantum Fourier transform preserves the commutation relations between the bilinear functions of the creation and annihilation operators. Based on the definition of the quantum Fourier transform introduced in the framework of the Ising model, two of its special cases are considered. It is shown that one particular case of the quantum Fourier transform is realized in the model of a symmetric beam splitter.
