Beyond islands: A free probabilistic approach

Jinzhao Wang

We give a free probabilistic proposal to compute the fine-grained radiation entropy for an arbitrary bulk radiation state, in the context of the Penington-Shenker-Stanford-Yang (PS…

The black hole information puzzle and the quantum de Finetti theorem

Renato Renner, Jinzhao Wang

The black hole information puzzle arises from a discrepancy between conclusions drawn from general relativity and quantum theory about the nature of the radiation emitted by a blac…

The refined quantum extremal surface prescription from the asymptotic equipartition property

Jinzhao Wang

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

On the horizon entropy of a causal set

Ludovico Machet, Jinzhao Wang

We discuss how to define a kinematical horizon entropy on a causal set. We extend a recent definition of horizon molecules to a setting with a null hypersurface crossing the horizo…

Revisiting the equality conditions of the data processing inequality for the sandwiched Rényi divergence

Jinzhao Wang, Henrik Wilming

We provide a transparent, simple and unified treatment of recent results on the equality conditions for the data processing inequality (DPI) of the sandwiched quantum Rényi diverge…

On the continuum limit of Benincasa-Dowker-Glaser causal set action

Ludovico Machet, Jinzhao Wang

We study the continuum limit of the Benincasa-Dowker-Glaser causal set action on a causally convex compact region. In particular, we compute the action of a causal set randomly spr…

Outer entropy = Bartnik-Bray inner mass, and the gravitational ant conjecture

Jinzhao Wang

Entropy and energy are found to be closely tied on our quest for quantum gravity. We point out an interesting connection between the recently proposed outer entropy, a coarse-grain…

The small sphere limit of quasilocal energy in higher dimensions along lightcone cuts

Jinzhao Wang

The problem of quasilocal energy has been extensively studied mainly in four dimensions. Here we report results regarding the quasilocal energy in spacetime dimension . Af…

Local gravitational energy in higher dimensions

Jinzhao Wang

In general relativity, the local gravitational energy is best characterised by the quasilocal mass. The small sphere limit of quasilocal mass provides us the most local notion of g…

Geometry of small causal diamonds

Jinzhao Wang

The geometry of small causal diamonds is systematically studied, based on three distinct constructions that are common in the literature, namely the geodesic ball, the Alexandrov i…

Confidence Polytopes in Quantum State Tomography

Jinzhao Wang, Volkher B. Scholz, Renato Renner

Quantum State Tomography is the task of inferring the state of a quantum system from measurement data. A reliable tomography scheme should not only report an estimate for that stat…
