论文摘要
Qutrit（三级原子系统）的比较研究与典型的马尔可夫储层（自由空间）和光子带隙（PBG）晶体中的经典场相结合。该研究的目的是评估结构化环境的集体影响和对系统对量子相干性，非马克维亚性动态的经典控制以及最初在原子状态编码的参数的估计。我们表明，与驱动的Qutrit在马尔可夫环境中相比，PBG材料作为系统的媒介和经典驾驶场的建设性相互作用会导致所有感兴趣的量子特征的显着增强。我们的结果提供了在QUTRIT系统中保存和增强量子特征的见解，这些量子系统有望在量子处理器而不是Qubits中使用替代候选者。
A comparative study of a qutrit (three-level atomic system) coupled to a classical field in a typical Markovian reservoir (free space) and in a photonic band-gap (PBG) crystal is carried out. The aim of the study is to assess the collective impact of structured environment and classical control of the system on the dynamics of quantum coherence, non-Markovianity, and estimation of parameters which are initially encoded in the atomic state. We show that the constructive interplay of PBG material as a medium and classical driving field as a part of system results in a significant enhancement of all the quantum traits of interest, compared to the case when the driven qutrit is in a Markovian environment. Our results supply insights for preserving and enhancing quantum features in qutrit systems which are promising alternative candidates to be used in quantum processors instead of qubits.
