The JLMS formula in a large code with approximate error correction
The paper addresses limitations of using Gauge/Gravity duality as an exact quantum error-correcting code, specifically concerning the JLMS formula. Instead of requiring $G o 0$, it constructs a single 'large' code assembled from many small codes. This allows for approximate recovery of entanglement wedge information even when $G$ is not infinitesimally small.
