AI中文摘要：
研究了史瓦西时空中两量子比特各向同性态在霍金辐射和环境退相干下的波特征、粒子特征及混合度的重新分布情况。结果表明，霍金辐射会改变它们在不同视界区域的相对权重，而非仅简单抑制；分析进一步扩展到相位阻尼、相位翻转和比特翻转通道：相位阻尼单调抑制波特征并增强混合度，相位翻转使波特征呈现对称的消灭与复兴行为，比特翻转主要通过对角布局重新分布重塑粒子特征与混合度。不过，尽管霍金辐射和通道噪声会影响子系统中波特征、粒子特征及混合度的分布，三者间的三元关系仍然成立，不受热噪声和环境噪声影响。
英文摘要：
The redistribution of the wave feature, particle feature, and mixedness is investigated for two-qubit isotropic states in Schwarzschild spacetime under Hawking radiation and environmental decoherence. It is shown that Hawking radiation changes their relative weights among different horizon regions rather than simply suppressing them. The analysis is further extended to phase damping, phase flip, and bit flip channels. Phase damping monotonically suppresses the wave feature and enhances mixedness, phase flip produces a symmetric death-and-revival behavior of the wave feature, and bit flip mainly reshapes the particle feature and mixedness through diagonal population redistribution. However, although Hawking radiation and channel noise affect the distribution of wave feature, particle feature, and mixedness in the subsystems, the triality relation among them still holds and remains unaffected by thermal and environmental noises.
