我们研究了黑洞量子大气中三方混合态的量子态纹理、真正的多方纠缠和三方非定域性。通过将哈特尔 - 霍金局部温度引入博戈留波夫系数，我们刻画了局部霍金效应对于可及和不可及约化态的影响。我们发现这三个量的极值都位于同一近视界区域，且随局部霍金温度升高向外移动，与局部霍金温度的峰值区域重合，表明三方量子信息的不同方面在同一大气区域对局部霍金效应最为敏感。与真正的多方纠缠不同，三方非定域性更脆弱，在更强的局部霍金效应下会被抑制。这些结果为受黑洞量子大气影响的三方混合态中的密度矩阵重构、纠缠再分布和非定域性提供了统一的刻画。
英文摘要
We investigate quantum state texture, genuine multipartite entanglement, and tripartite nonlocality of a tripartite mixed state in the black hole quantum atmosphere. By introducing the Hartle-Hawking local temperature into the Bogoliubov coefficients, we characterize the influence of the local Hawking effect on both physically accessible and inaccessible reduced states. We find that the extrema of these three quantities all lie in the same near horizon region and shift outward with increasing local Hawking temperature, coinciding with the peak region of the local Hawking temperature and indicating that different aspects of tripartite quantum information are most sensitive to the local Hawking effect in the same atmospheric region. In contrast to genuine multipartite entanglement, tripartite nonlocality is more fragile and is suppressed under stronger local Hawking effects. These results provide a unified characterization of density matrix restructuring, entanglement redistribution, and nonlocality in tripartite mixed states affected by the black hole quantum atmosphere.
