论文摘要
量子相干性，量子纠缠和量子非局部性是量子信息进攻中的重要资源。但是，当量子系统与外部环境相互作用时，会发生变质。我们研究一个和/或两个量子位经历偏移时，在非惯性框架中类似于非惯性框架中的三分之一GHz状态的动力学演变。在振幅阻尼通道下，我们表明量子的反应性和隔离效应可能对初始状态具有截然不同的影响。此外，真正的三方纠缠和量子连贯性在进化过程中可能会突然死亡。量子相干性最能抵抗量子反应性和未造成效果，然后是量子纠缠和量子非局部性，这在三个中最脆弱。结果为相对论量子信息学提供了新的研究观点。
Quantum coherence, quantum entanglement and quantum nonlocality are important resources in quantum information precessing. However, decoherence happens when a quantum system interacts with the external environments. We study the dynamical evolution of the three-qubit GHZ-like states in non-inertial frame when one and/or two qubits undergo decoherence. Under the amplitude damping channel we show that the quantum decoherence and the Unruh effect may have quite different influences on the initial state. Moreover, the genuine tripartite entanglement and the quantum coherence may suffer sudden death during the evolution. The quantum coherence is most resistent to the quantum decoherence and the Unruh effect, then comes the quantum entanglement and the quantum nonlocality which is most fragile among the three. The results provide a new research perspective for relativistic quantum informatics.
