黑洞中的高斯量子操纵

Gaussian quantum steering under the influence of a dilaton black hole

Biwei Hu, Cuihong Wen, Jieci Wang, Jiliang Jing

摘要:

研究了在Garfinkle-Horowitz-Strominger介子黑洞背景下高斯量子操纵的动力学.研究发现,由于引力场的作用,惯性观测者Alice和处于事件视界外的观测者Bob之间的量子可操纵性被破坏,而因果不连通区域之间则产生了操纵型量子关联.因此,即使观测者被事件视界隔开,也可以通过局部测量来控制彼此的状态。与介子时空中的量子纠缠不同,量子操纵随着介子电荷的增加而经历“突然死亡”和“突然诞生”等灾难性行为。另外,玻色子引力破坏了高斯转向的对称性,使得后者在膨胀时空中总是不对称的。有趣的是,达到最大的转向不对称性表明单向和双向转向之间的临界点的双模高斯态在介子时空。

英文摘要:

We study the dynamics of Gaussian quantum steering in the background of a Garfinkle-Horowitz-Strominger dilaton black hole. It is found that the gravity induced by dilaton field will destroy the quantum steerability between the inertial observer Alice and the observer Bob who hovers outside the event horizon, while it generates steering-type quantum correlations between the causally disconnected regions. Therefore, the observers can steer each other's state by local measurements even though they are separated by the event horizon. Unlike quantum entanglement in the dilaton spacetime, the quantum steering experiences catastrophic behaviors such as "sudden death" and "sudden birth" with increasing dilaton charge. In addition, the dilaton gravity destroys the symmetry of Gaussian steering and the latter is always asymmetric in the dilation spacetime. Interestingly, the attainment of maximal steering asymmetry indicates the critical point between one-way and two-way steering for the two-mode Gaussian state in the dilaton spacetime.
