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.
Highlights
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
In the current work, we study the pattern of the orthogonality speed in a novel system consisting of a ballistic nanowire excited by Rashba spin-orbit coupling (RSOC) in the presence or absence the perpendicular magnetic fields when system’s initial states are prepared in several forms: pure state, maximum entangled state, and superposition state
This paper is organized as follows: In “The physical model” section, we offer an analytical solution to the physical model when three distinct types of magnetic fields are employed to the nanowire system with RSOC
