Can we identify a task in which quantum-gravity effects play an essential role?

Statement

Problem 2.4 of Goto et al.: since AdS/CFT is expected to hold beyond the infinite-$N$ limit, are there information-processing tasks whose performance is enhanced or degraded by genuinely quantum-gravitational ($1/N$, stringy) effects — as opposed to semiclassical ones?

Why It Matters

Peripheral to the group’s programs, which live in the semiclassical / free-field regime. It is included for completeness of the paper’s Theme 1 and as a marker of where “beyond semiclassical” would take the group’s operational questions.

What We Know

• Most holographic-QI results (RT, QES, Page curve) are leading-order in $1/N$ (semiclassical).
• Candidate genuinely-quantum-gravity effects: non-perturbative saddles, doubly non-perturbative $e^{-1/G}$ corrections, stringy modifications of scrambling.

Possible Approaches

• Look for tasks whose optimal rate changes at subleading order in $1/N$.
• Use soluble models (double-scaled SYK, JT) where finite-$N$ bulk Hilbert spaces are accessible.
