Title: Quantum Channel Capacity of Traversable Wormhole
Abstract: We formulate the Gao-Jafferis-Wall traversable-wormhole protocol as a quantum channel and compute its quantum channel capacity. We show that this capacity is governed by the time derivative of an out-of-time-order correlator, hence by operator-size growth in the holographic dual, and that its growth is bounded above by the Einstein-gravity limit. The channel capacity therefore provides a natural benchmark for quantum simulations of traversable wormholes.
