我们提出了一种基于储层工程的防止量子相干性泄漏到浴槽的方案,该方案中我们用非调和振子强烈地干扰洛伦兹浴槽。我们发现,强烈的扰动改变了量子阱的光谱,降低了量子阱与量子阱的相互作用。此外,我们还利用主方程给出了精确的洛伦兹谱时间演化,并计算了量子比特的并发和生存概率,以证明强浴扰动对相干保护的影响。同时,与旋转波近似的结果相比,我们揭示了反向旋转相互作用对量子比特的动态影响。
We put forward a scheme based on reservoir engineering to protect quantum coherence from leaking to bath, in which we intensely disturb the Lorentzian bath byNharmonic oscillators. We show that the intense disturbance changes the spectrum of the bath and reduces the qubit–bath interaction. Furthermore, we give the exact time evolution with the Lorentzian spectrum by a master equation and calculate the concurrence and survival probability of the qubits to demonstrate the effect of the intense bath disturbance on the protection of coherence. Meanwhile, we reveal the dynamic effects of counter-rotating interaction on the qubits as compared to the results of the rotating-wave approximation.
