论文摘要
我们研究了相对论效应对量子系统进化速度以及振幅阻尼通道的作用。我们发现，相对论效应加快了量子的演变，以降级量子系统的均匀进化速度，用于阻尼参数$p_τ\ lysesim p_ {τ_{τ_{c0}}。 p_τ\ Lessim p_ {τ_{C1}}，$，其中相对论效应首先加速，然后减慢阻尼系统的量子演化过程。对于阻尼强度$ P_ {τ_{C1}} \ LessimP_τ$，我们观察到QSLT的单调增加行为，从而减慢了阻尼系统的量子演化。此外，我们研究了相对论效应对与相阻尼通道结合的系统的速度限制时间的作用。
We investigate the roles of the relativistic effect on the speed of evolution of a quantum system coupled with amplitude damping channels. We find that the relativistic effect speed-up the quantum evolution to a uniform evolution speed of open quantum systems for the damping parameter $p_τ\lesssim p_{τ_{c0}}.$ Moreover, we point out a non-monotonic behavior of the quantum speed limit time (QSLT) with acceleration in the damping limit $p_{τ_{c0}}\lesssim p_τ\lesssim p_{τ_{c1}},$ where the relativistic effect first speed-up and then slow down the quantum evolution process of the damped system. For the damping strength $p_{τ_{c1}}\lesssim p_τ$, we observe a monotonic increasing behavior of QSLT, leads to slow down the quantum evolution of the damped system. In addition, we examine the roles of the relativistic effect on the speed limit time for a system coupled with the phase damping channels.
