Description
Some aspects concerning coherence in open quantum systems remain poorly understood. On the one hand, coherence leads to entanglement and nonlocality. On the other, it leads to a suppression of fluctuations, causing violations of classical thermo-kinetic uncertainty relations. These represent its different manifestations, one depending only on the state of the system and one depending on two-time correlation functions. We employ these manifestations to determine when mesoscopic quantum transport through a double quantum dot can be captured by a classical jump model, and when such model breaks down implying nonclassical behavior. Quantum tunneling induces Rabi oscillations and results in both manifestations of coherence, indicating the breakdown of a classical description.
