Quantum Fourier transform is the building block for creating entanglement

This study demonstrates entanglement can be exclusively constituted by quantum Fourier transform (QFT) blocks. A bridge between entanglement and QFT will allow incorporating a spectral analysis to the already traditional temporal approach of entanglement, which will result in the development of new more performant, and fault-tolerant protocols to be used in quantum computing as well as quantum communication, with particular emphasis in the future quantum Internet.

Automated summary

This study shows that entanglement can be exclusively formed by quantum Fourier transform (QFT) blocks and establishes a connection between entanglement and QFT. Incorporating spectral analysis into the traditional temporal approach of entanglement can lead to the development of more efficient and fault-tolerant protocols for use in quantum computing and communication, particularly in the future quantum Internet.
