论文摘要
我们表明，强量子纠缠可以支持稳定的可穿越的虫洞，而无需在虫洞的两个边界理论之间进行任何明确的相互作用或隧道术语。具体来说，我们与两个复杂的SYK模型一起工作。纠缠状态是在假想时间内使用隧道术语制备的，但是从时间演化运算符中删除了隧道术语，因此两个复杂的SYK模型未耦合。低温状态显示复兴动态，这是可遍历虫洞几何形状的标志。要将任何有意义的信息从一个系统发送到另一个系统，一个人只需要打开一个很小的交互项即可。我们使用的技术可以应用于其他系统来研究量子纠缠的各个方面。
We show that strong quantum entanglement can support a stable traversable wormhole without any explicit interaction or tunnelling term between the two boundary theories of the wormhole. Specifically we work with two complex SYK models. The entangled state is prepared using a tunnelling term in imaginary time but the tunnelling term is removed from the time evolution operator so the two complex SYK models are not coupled. Low temperature states show revival dynamics which is the hallmark of a traversable wormhole geometry. To send any meaningful information from one system to the other, one only needs to turn on a very small interaction term. The technique that we are employing can be applied to other systems to study aspects of quantum entanglement.
