We investigate the feasibility of using an effective pulse control methods to realize an almost exact state transmission through a uniform chain where the communication channel is immersed in a quantum environment. This pulse control is treated in a non-perturbative fashion, allowing for a more precise view. Using the non-Markovian quantum state diffusion equation, we calculate the dynamics of the transmission fidelity. The results show that the memory effects of the environment can support an effective transmission control that can be boosted under a non-Markovian environment. Our scheme provides another way to realize almost exact state transmission in a spin chain system.

我们研究了使用有效的脉冲控制方法通过一条均匀的链实现几乎精确的状态传输的可行性，在该链中，通信通道沉浸在量子环境中。此脉冲控制采用非扰动方式处理，从而可以提供更精确的视图。使用非马尔可夫量子态扩散方程，我们计算了传输保真度的动力学。结果表明，环境的记忆效应可以支持有效的传输控制，该控制可以在非马尔可夫环境下得到增强。我们的方案提供了在自旋链系统中实现几乎精确的状态传输的另一种方法。
