Entanglement parallelization via quantum Fourier transform
In this study, we present a technique based on the quantum Fourier transform
(QFT) that allows the generation of disjoint sets of entangled particles, 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 were specially
selected due to their particular commitment to the future Quantum Internet.
