Abstract

Unlike standard quantum teleportation, the many-body teleportation protocol works by spreading information across a large number of degrees of freedom. The protocol originates from a microscopic realization of holographic traversable wormholes and has been shown to be useful for diagnosing scrambling when the out-of-time-order (OTOC) correlator isn't sufficient. In addition, it can distinguish different scrambling behaviors, with holographic systems thought to rely on a unique mechanism. Holography predicts that using the same protocol, information can travel between two boundaries of a spacetime having a multi-boundary wormhole. In this work, we explore the teleportation protocol for qubit systems in the infinite temperature three-boundary setting and observe new features that resemble the holographic phenomenon of causal shadows. Adding the third boundary provides further spatial resolution to the dynamics of information spreading.
