Quantum computational speed of a nanowires system with Rashba interaction in the presence of a magnetic field

Abstract

The present research is designed to examine the dynamic of the quantum computational speed in a nanowire system through the orthogonality speed when three distinct types of magnetic fields are applied: the strong magnetic field, the weak magnetic field, and no magnetic field. Moreover, we investigate the action of the magnetic fields, the spin-orbit coupling, and the system’s initial states on the orthogonality speed. The observed results reveal that a substantial correlation between the intensity of the spin-orbit coupling and the dynamics of the orthogonality speed, where the orthogonality speed decreasing as the spin-orbit coupling increases. Furthermore, the initial states of the nanowire system are critical for regulating the speed of transmuting the information and computations.

Nanowires: Exponential speedup in quantum computing

“…Qubits, the building blocks of quantum information, are transported through nanowires in quantum computing [ 3 , 4 ]. Their nanoscale size makes it possible to precisely regulate quantum states, which makes it easier to construct quantum gates and improves coherence [ 5 , 6 ]. To optimize quantum computer systems, researchers are investigating a variety of materials for nanowire production, including semiconductors and superconductors.…”
