The passage around this formula
…branch has ticked through more proper time, and that correlation decoheres the superposition at a rate fixed by the local gravitational gradient and the system’s own internal energy spread [ 15 ] . Near a horizon, where f(r) varies far more sharply with height than at a laboratory bench on Earth, the relevant gradient is not a small perturbative correction; it is set by the same that redshifts everything else in this ledger. The effect does not respect the static/free-fall distinction drawn above: a…
