两个遥远的黑洞可以通过虫洞在内部相连。这样的虫洞被解释为两个外部区域共享的纠缠态。如果爱丽丝和鲍勃向每个黑洞发送信号，他们就可以在黑洞内部相遇。在这封信中，我们用准备纠缠态的量子电路来解释这次相遇：爱丽丝和鲍勃发送信号在电路中产生越来越大的微扰，这些微扰的重叠代表着他们在虫洞内相遇。我们认为，电路中的这种重叠是由特定的六点关联函数来量化的。因此，拥有纠缠量子比特的外部观察者可以使用这种关联函数来诊断内部的碰撞，而不必自己跳进去。
Two distant black holes can be connected in the interior through a wormhole. Such a wormhole has been interpreted as an entangled state shared between two exterior regions. If Alice and Bob send signals into each of the black holes, they can meet in the interior. In this letter, we interpret this meeting in terms of the quantum circuit that prepares the entangled state: Alice and Bob sending signals creates growing perturbations in the circuit, whose overlap represents their meeting inside the wormhole. We argue that such overlap in the circuit is quantified by a particular six-point correlation function. Therefore, exterior observers in possession of the entangled qubits can use this correlation function to diagnose the collision in the interior without having to jump in themselves.
