论文摘要
最佳发动机性能是通过量子效应完成的。在这里,我们探索了通向理想发动机的两条路线,即(1)量子系统,它们可以用作混合机器能够执行多个有用的任务,以及(2)在执行此类任务时抑制波动的情况。对于经典设备,不存在波动是由高熵产生来调节的,因为决定了热力学不确定性关系。在这里,我们将这种关系概括为作为混合热机的多发导体。当我们证明与正常金属接触的双量子点和储层是纠缠库珀对的发电机时,我们证明了这些关系在量子导体中被克服。
Optimal engine performances are accomplished by quantum effects. Here we explore two routes towards ideal engines, namely (1) quantum systems that operate as hybrid machines being able to perform more than one useful task and (2) the suppression of fluctuations in doing such tasks. For classical devices, the absence of fluctuations is conditioned by a high entropy production as dictate the thermodynamic uncertainty relations. Here we generalize such relations for multiterminal conductors that operate as hybrid thermal machines. These relations are overcome in quantum conductors as we demonstrate for a double quantum dot contacted to normal metals and a reservoir being a generator of entangled Cooper pairs.
