On the Quantum Fourier Transform in the Ising and Beam Splitter Models
... 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.
