论文摘要
研究了相协变量图的量子进化速度。这涉及吸收，排放和脱落过程。我们考虑上述过程的各种组合下的地图，以研究相协变量图对量子速度限制时间的影响。对于无吸收相的协变量图，考虑了耗散性和CP-（IN）可分解的（非） - mmarkovian dephasing噪声的组合。在存在真空和有限温度效应的情况下，检查相干混合平衡对速度限制时间的作用。我们还研究了孔的信息的变化和相协变量图的特定情况的进化速度的速率。
The quantum speed of evolution for the phase covariant map is investigated. This involves absorption, emission and dephasing processes. We consider the maps under various combinations of the above processes to investigate the effect of phase covariant maps on quantum speed limit time. For absorption-free phase covariant maps, combinations of dissipative and CP-(in)divisible (non)-Markovian dephasing noises are considered. The role of coherence-mixedness balance on the speed limit time is checked in the presence of both vacuum and finite temperature effects. We also investigate the rate at which Holevo's information changes and the action quantum speed of evolution for specific cases of the phase covariant map.
