Abstract
The effects of optical polarons on qubit coherence times in a RbCl quantum dot (QD) under a pseudoharmonic potential (PHP) are theoretically investigated using Fermi’s Golden Rule and Pekar type variational method (PTVM). From this, coherence time variations are analytically driven as a function of the chemical potential (CP) of two-dimensional electron gas (2DEG), polaron radius and PHP zero point, which are shown to have a significant impact. Our results provide a theoretical method for solving stability issues with qubits during quantum information.
