论文摘要
使用Lindblad方程方法，我们得出了相互作用的一维电子链的参数的范围，该参数连接到两个较大的偏见极限，其中最佳工作点（对应于固定电流的单调性作为施加偏见的函数的单调性变化）在非Quilibribiribiribiribirium Interary Interary Interary Intary Intary Intary Intary Intary Intary Intary Intary Intartary Intartary Intartary。在一维无旋转的费米式哈伯德链的特定情况下，我们证明，在固定电流对链和储层之间的耦合的依赖性中，在相互作用和非互动情况下都出现了最佳的工作点。我们表明，最佳工作点与链的局部缺陷以及有限量的淬火障碍相对于稳健。最终，我们通过尽可能接近其最佳工作点来调整其组件来讨论结果对优化量子电路性能的重要性。
Using the Lindblad equation approach, we derive the range of the parameters of an interacting one-dimensional electronic chain connected to two reservoirs in the large bias limit in which an optimal working point (corresponding to a change in the monotonicity of the stationary current as a function of the applied bias) emerges in the nonequilibrium stationary state. In the specific case of the one-dimensional spinless fermionic Hubbard chain, we prove that an optimal working point emerges in the dependence of the stationary current on the coupling between the chain and the reservoirs, both in the interacting and in the noninteracting case. We show that the optimal working point is robust against localized defects of the chain, as well as against a limited amount of quenched disorder. Eventually, we discuss the importance of our results for optimizing the performance of a quantum circuit by tuning its components as close as possible to their optimal working point.
