The refined quantum extremal surface prescription from the asymptotic equipartition property

Understand

Information-theoretic ideas have provided numerous insights in the progress of fundamental physics, especially in our pursuit of quantum gravity.

• In particular, the holographic entanglement entropy is a very useful tool in studying AdS/CFT, and its efficacy is manifested in the recent black hole page curve calculation.
• On the other hand, the one-shot information-theoretic entropies, such as the smooth min/max-entropies, are less discussed in AdS/CFT.
• They are however more fundamental entropy measures from the quantum information perspective and should also play pivotal roles in holography.
