Query: One-shot decoupling and Page curves from a dynamical model for black
  hole evaporation   One-shot decoupling is a powerful primitive in quantum information theory and
was hypothesized to play a role in the black hole information paradox. We study
black hole dynamics modeled by a trilinear Hamiltonian whose semiclassical
limit gives rise to Hawking radiation. An explicit numerical calculation of the
discretized path integral of the S-matrix shows that decoupling is exact in the
continuous limit, implying that quantum information is perfectly transferred
from the black hole to radiation. A striking consequence of decoupling is the
emergence of an output radiation entropy profile that follows Page's
prediction. We argue that information transfer and the emergence of Page curves
is a robust feature of any multi-linear interaction Hamiltonian with a bounded
spectrum.
