Entanglement Parallelization via Quantum Fourier Transform

Abstract

In this study, a technique based on the quantum Fourier transform (QFT) that allows the generation of disjoint sets of entangled particles is presented, in such a way that particles of the same set are entangled with each other, while particles of different sets are completely independent. Several applications of this technique are implemented on three physical platforms, of 5 (Belem), 7 (Oslo), and 14 (Melbourne) qubits, of the international business machine (IBM Q) quantum experience program, where all these applications are specially selected due to their particular commitment to the future Quantum Internet.

“…On the other hand, to the right of Figure 2, a model of both Type-I crystals can be seen, which are joined, one after the other, in an orientation sequence {0º, 90º}. The aforementioned modeling is carried out from the multiplication of two blocks of the flipped quantum Fourier transform (QFTf) type, where the rows of the first are multiplied by the columns of the second, resulting in a Feynman's gate [12][13][14][15][16][17]. Then, being,…”
