AI 中文摘要
长期以来,人们一直认为,一个粒子在穿过黑洞事件视界时,若未与外部宇宙中的另一个粒子发生纠缠,就无法再与该粒子发生动态纠缠。在此,我们在引力推迟势模型中证明,实际上可以在穿越事件视界的自由下落空间叠加态之间从头产生纠缠。然而,要径向提取该态需要非惯性减速,这会触发软引力子轫致辐射,并根据纠缠相位建立严格的退相干界:Γ≥729/(160π)Φ,这会使纠缠态退相干。相比之下,等效的宏观光学质量可通过量子擦除实现对纠缠的局域切向提取,从而揭示出一种显著的几何对偶性:当局域质量被拖离视界时,时空会不可逆地降解纠缠,同时允许其纠缠态横向传输到无穷远。
英文摘要
It has long been assumed that a particle--having crossed a black hole event horizon unentangled with another particle in the exterior universe--can no longer dynamically entangle with that particle. Here, we first establish the possibility of post-crossing entanglement via an electromagnetic mediator. We then show within a gravitational time-delayed-potential model that entanglement can be created between freely falling spatial superpositions across an event horizon. Radial escape, however, triggers bremsstrahlung emission--imposing a dephasing bound that grows with entangling phase, $Γ> \frac{6}{11π}Φ$, within a constrained leading-quadrupole model--and is ultimately ruled out by macroscopic which-path leakage. By contrast, equivalent macroscopic optical masses in principle allow local harvesting of entanglement tangentially, via quantum erasure, thus revealing a remarkable geometric duality: Spacetime irreversibly degrades entanglement under radial escape, while allowing the transverse teleportation of the entangled qubit to infinity, independent of Hawking evaporation.
CommentsA new electromagnetic mediation scenario replaces the previous one, more comparable to the gravitational one. The manuscript has 12 pages, 4 figures, 3 appendices
