  The Schwarzschild wormhole has been interpreted as an entangled state. If
Alice and Bob fall into each of the black hole, they can meet in the interior.
We interpret this meeting in terms of the quantum circuit that prepares the
entangled state. Alice and Bob create growing perturbations in the circuit, and
we argue that the overlap of these perturbations represents their meeting. We
compare the gravity picture with circuit analysis, and identify the
post-collision region as the region storing the gates that are not affected by
any of the perturbations.
