Although quantum coherence is a well known phenomenon in quantum information theory and quantum optics, it has been investigated from the resource theory perspective only recently. Furthermore, quantum coherence has important implications in relativistic quantum information where the degradation of entanglement can be attributed to decoherence. In this paper, we investigate the quantum coherence of $\left(1+1\right)$ Dirac field modes localized in a cavity as observed by two relatively accelerated observers. The acceleration is assigned very small values and its effects are investigated in a perturbative regime. For this purpose, we use $\alpha$ parameterized two-qubit pure entangled state and a Werner state. We find that coherence shows a periodic degradation due to accelerated motion. However, this degradation can be balanced by adjusting the durations of uniform and accelerated motion. Moreover, it is found that dynamics of quantum coherence closely resembles that of entanglement under the same settings. This similarity confirms the recent attempts to relate the resource theories of coherence and entanglement in a relativistic regime.

尽管量子相干在量子信息论和量子光学中是众所周知的现象，但直到最近才从资源论的角度对其进行研究。此外，量子相干性在相对论量子信息中具有重要意义，其中纠缠的恶化可归因于去相干性。在本文中，我们研究了量子点的量子相干性$\left(\mathrm{1个}+\mathrm{1个}\right)$由两个相对加速的观察者观察到的狄拉克场模式位于腔中。加速度被指定为很小的值，并且在摄动状态下研究了其影响。为此，我们使用$\alpha$参数化的两比特纯纠缠态和Werner态。我们发现相干性由于加速运动而显示出周期性的下降。但是，可以通过调整均匀运动和加速运动的持续时间来平衡这种退化。此外，发现在相同的设置下，量子相干动力学与纠缠动力学非常相似。这种相似性证实了最近尝试将相对论体系中的连贯性和纠缠性资源理论联系起来的尝试。
