A bstractWe study Renyi entropies Sn in quantum error correcting codes and compare the answer to the cosmic brane prescription for computing S˜n≡n2∂nn−1nSn$$ {\tilde{S}}_n\equiv {n}^2{\partial}_n\left(\frac{n-1}{n}{S}_n\right) $$. We find that general operator algebra codes have a similar, more general prescription. Notably, for the AdS/CFT code to match the specific cosmic brane prescription, the code must have maximal entanglement within eigenspaces of the area operator. This gives us an…

One-loop universality of holographic codes
Recent work showed holographic error correcting codes to have simple universal features at O (1 /G ). In particular, states of fixed Ryu-Takayanagi (RT) area in such codes are associated with flat

In holographic theories, the reflected entropy has been shown to be dual to the area of the entanglement wedge cross section. We study the same problem in random tensor networks demonstrating an

Holographic proof of the strong subadditivity of entanglement entropy
When a quantum system is divided into subsystems, their entanglement entropies are subject to an inequality known as strong subadditivity. For a field theory this inequality can be stated as follows:
