论文摘要
我们研究热环境对旋转轨矩形旋转式旋转速度的非绝热自旋驱动方案的影响。在存在时间依赖的自旋轨道相互作用的情况下，驾驶协议通过移动量子沿纳米线沿谐波电势陷入谐波电势而运行。我们认为谐波的自由度弱耦合到热浴。我们找到了Floquet状态的分析表达式，并得出了强烈非绝热驱动量子的Lindblad方程。 Lindblad方程用羔羊移动项和耗散行为纠正了孤立的量子的动力学。使用lindblad方程，分析了热环境对自旋叉协议的影响。
We study the influence of a thermal environment on a non-adiabatic spin-flip driving protocol of spin-orbit qubits. The driving protocol operates by moving the qubit, trapped in a harmonic potential, along a nanowire in the presence of a time-dependent spin-orbit interaction. We consider the harmonic degrees of freedom to be weakly coupled to a thermal bath. We find an analytical expression for the Floquet states and derive the Lindblad equation for a strongly non-adiabatically driven qubit. The Lindblad equation corrects the dynamics of an isolated qubit with Lamb shift terms and a dissipative behaviour. Using the Lindblad equation, the influence of a thermal environment on the spin-flip protocol is analysed.
