- Abstract summary: Quantum states with dual geometrics are known to satisfy a stricter set of entropy inequalities than general quantum systems.
These inequalities are no longer satisfied once general quantum corrections are included.
We show that requiring the bulk entropies to satisfy the HEC implies that the boundary entropies also satisfy the HEC.

- Abstract: Quantum states with geometric duals are known to satisfy a stricter set of
entropy inequalities than those obeyed by general quantum systems. The set of
allowed entropies derived using the Ryu-Takayanagi (RT) formula defines the
Holographic Entropy Cone (HEC). These inequalities are no longer satisfied once
general quantum corrections are included by employing the Quantum Extremal
Surface (QES) prescription. Nevertheless, the structure of the QES formula
allows for a controlled study of how quantum contributions from bulk entropies
interplay with HEC inequalities. In this paper, we initiate an exploration of
this problem by relating bulk entropy constraints to boundary entropy
inequalities. In particular, we show that requiring the bulk entropies to
satisfy the HEC implies that the boundary entropies also satisfy the HEC.
Further, we also show that requiring the bulk entropies to obey monogamy of
mutual information (MMI) implies the boundary entropies also obey MMI.

We introduce a comprehensive family of conditional entropies that reveals a unified structure underlying all previously studied forms of quantum conditional R'enyi entropies.
This new family satisfies a range of desiderata, including data processing inequalities, additivity under tensor products, duality relations, chain rules, concavity or convexity, and various parameter monotonicity relations.
We expect this family of entropies, along with our generalized chain rules, to find applications in quantum cryptography and information theory.

I prove that it satisfies the data processing inequality, and the method of proof relies upon the operator Jensen inequality.
One benefit of this approach is that there is now a single, unified approach for establishing the data processing inequality for the Petz--Renyi and sandwiched Renyi relative entropies.
