    "abstract": "We consider a bipartite entangled system half of which falls through the\nevent horizon of an evaporating black hole, while the other half remains\ncoherently accessible to experiments in the exterior region. Beyond complete\nevaporation, the evolution of the quantum state past the Cauchy horizon cannot\nremain unitary, raising the questions: How can this evolution be described as a\nquantum map, and how is causality preserved? The answers are subtle, and are\nlinked in unexpected ways to the fundamental laws of quantum mechanics. We show\nthat terrestrial experiments can be designed to constrain exactly how these\nlaws might be altered by evaporation.",
