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.

具有二维伪谐波电位的RbCl量子点中光极化子对量子位相干时间的影响

理论上使用费米黄金定律和佩卡尔型变分法（PTVM）研究了光学极化子对拟谐波势（PHP）下RbCl量子点（QD）中量子位相干时间的影响。据此，相干时间变化是根据二维电子气（2DEG），极化子半径和PHP零点的化学势（CP）的函数来驱动的，这些函数显示出显着的影响。我们的结果提供了一种解决量子信息过程中量子位稳定性问题的理论方法。
