Universal trapping law induced by atomic cloud in single-photon cooperative dynamics
Lei Qiao, Chang-Pu Sun
Single-photon cooperative dynamics of an assembly of two-level quantum emitters coupled by a bosonic bath are investigated. The bosonic bath is general and it can be anything as lo…
Directional quantum random walk induced by coherence
Jin-Fu Chen, Yu-Han Ma, Chang-Pu Sun
Quantum walk (QW), which is considered as the quantum counterpart of the classical random walk (CRW), is actually the quantum extension of CRW from the single-coin interpretation.…
Boosting the performance of the Quantum Otto heat engines
Jin-Fu Chen, Chang-Pu Sun, Hui Dong
To optimize the performance of a heat engine in finite-time cycle, it is important to understand the finite-time effect of thermodynamic processes. Previously, we have shown that e…
Achieve Higher Efficiency at Maximum Power with Finite-time Quantum Otto Cycle
Jin-Fu Chen, Chang-Pu Sun, Hui Dong
The optimization of finite-time thermodynamic heat engines was intensively explored recently, yet limited to few cycles, e.g. finite-time Carnot-like cycle. In this paper, we suppl…
Uncertainties of genuinely incompatible triple measurements based on statistical distance
Hui-Hui Qin, Ting-Gui Zhang, Leonardo Jost +3
We investigate the measurement uncertainties of a triple of positive operator-valued measures (POVMs) based on statistical distance, and formulate state-independent tight uncertain…
