We argue that novel (highly nonclassical) quantum extremal surfaces play a crucial role in reconstructing the black hole interior even for isolated, single-sided, non-evaporating black holes (i.e. with no auxiliary reservoir). Specifically, any code subspace where interior outgoing modes can be excited will have a quantum extremal surface in its maximally mixed state. We argue that as a result, reconstruction of interior outgoing modes is always exponentially complex. Our construction provides evidence in favor of a strong Python's lunch proposal: that nonminimal quantum extremal surfaces are the exclusive source of exponential complexity in the holographic dictionary. We also comment on the relevance of these quantum extremal surfaces to the geometrization of state dependence in the typicality arguments for firewalls.

  1. Observer complementarity for black holes and holography

    hep-th 2025-07 conditional novelty 7.0 of 10

    The authors show that the observer rule of Harlow, Usatyuk, and Zhao yields a self-consistent black hole complementarity for both partially and fully evaporated black holes.

  2. On the stabilizer complexity of Hawking radiation

    hep-th 2025-10 conditional novelty 6.0 of 10

    In the PSSY model, the Wigner negativity (stabilizer magic) of Hawking radiation is O(1) before the Page time and grows as sqrt(2/pi) exp((S_max - S_2)/2) afterward; a similar formula is proposed for holographic state...

  3. Tests of restricted Quantum Focusing and a new CFT bound

    hep-th 2025-10 conditional novelty 6.0 of 10

    From rQFC, a new CFT bound follows that forbids the QNEC from saturating faster than O(Σ^{d−2}) in near-vacuum states, while rQFC is proven in JT gravity and explicit QFC counterexamples are constructed.

  4. Evaporating universes

    hep-th 2025-07 conditional novelty 6.0 of 10

    A toy model using four-dimensional Brill-Lindquist wormholes reproduces the Page curve for black hole evaporation and shows Hawking-radiation decoding complexity falls to polynomial at late times.

  5. On tests for baby universes in AdS/CFT

    hep-th 2025-07 conditional novelty 5.0 of 10

    With a post-selected holographic map for the baby universe, the Engelhardt-Gesteau swap test cannot distinguish the two candidate bulk duals.
