In this study, the bridge between quantum fourier transform (QFT) and the most important effect inside quantum physics—entanglement—is presented. Moreover, all the applications of entanglement are impregnated by this equivalence, which concludes in the first spectral approach to the quantum Internet of the literature, which will allow the development of configurations that are more immune to noise as well as fault-tolerant. Several protocols used in the quantum Internet are implemented on a 5-qubit international business machine quantum (IBM Q) platform, experimentally verifying the aforementioned equivalence.
