• Abstract: We study how energy and quantum entanglement are transferred when two identical CFTs are entangled locally. This is probed by considering a local operator insertion in one of the CFTs. When the CFTs have holographic duals via the AdS/CFT correspondence, the transfer happens through an AdS wormhole that allows signal propagation even beyond the horizon from one AdS boundary to the other; we demonstrate this in explicit CFT calculations. We argue that this transmission is possible because the insertion of a local operator is not a unitary process but a regularized version of projection measurement, and that this is interpreted as quantum teleportation. We also find that this leads to a phenomenon opposite to scrambling, where mutual information, instead of being suppressed, gets enhanced by the insertion of a local operator excitation.

  We study the dynamics of end-of-the-world (EOW) branes in AdS with scalar fields localized on the branes. This allows us to construct explicit solutions dual to boundary RG flows. We also obtain a variety of annulus-like or cone-like shaped EOW branes, which are not possible without the scalar field.

  In spherically symmetric states in any dimension and more general states in 2d CFT, this leads to a holographic error-correcting code. The code is shown to be isometric for light operators outside the horizon, and non-isometric inside. The transition at the horizon occurs due to a subtle breakdown of the Virasoro identity block approximation in states with a complex interior.
