Generalized Rényi Entropy Accumulation Theorem and Generalized Quantum Probability Estimation [PDF]
The entropy accumulation theorem—and its subsequent generalized version—is a powerful tool in the security analysis of many device-dependent and device-independent cryptography protocols. However, it has the drawback that the finite-size bounds it yields

A Generalized Equilibrium Transform with Application to Error Bounds in the Rényi Theorem with No Support Constraints [PDF]
We introduce a generalized stationary renewal distribution (also called the equilibrium transform) for arbitrary distributions with finite nonzero first moment and study its properties.

Holographic second laws of black hole thermodynamics
Recently, it has been shown that for out-of-equilibrium systems, there are additional constraints on thermodynamical evolution besides the ordinary second law.

A simple probabilistic construction yielding generalized entropies and divergences, escort distributions and q-Gaussians [PDF]
We give a simple probabilistic description of a transition between two states which leads to a generalized escort distribution. When the parameter of the distribution varies, it defines a parametric curve that we call an escort-path.

Spectra of large diluted but bushy random graphs [PDF]
We compute an asymptotic expansion in $1/c$ of the limit in $n$ of the empirical spectral measure of the adjacency matrix of an Erd\H{o}s-R\'enyi random graph with $n$ vertices and parameter $c/n$.

Strong entanglement distribution of quantum networks
Large-scale quantum networks have been employed to overcome practical constraints of transmission and storage for single entangled systems. Our goal in this paper is to explore the strong entanglement distribution of quantum networks.

Analytic and Asymptotic Properties of the Generalized Student and Generalized Lomax Distributions
Analytic and asymptotic properties of the generalized Student and generalized Lomax distributions are discussed, with the main focus on the representation of these distributions as scale mixtures of the laws that appear as limit distributions in ...

Universal thermal corrections to symmetry-resolved entanglement entropy and full counting statistics
In the presence of a global symmetry, the entanglement entropy of a quantum system can be decomposed among the individual symmetry sectors, dubbed symmetry-resolved entanglement entropy.

Samplers and Extractors for Unbounded Functions [PDF]
Blasiok (SODA\u2718) recently introduced the notion of a subgaussian sampler, defined as an averaging sampler for approximating the mean of functions f from {0,1}^m to the real numbers such that f(U_m) has subgaussian tails, and asked for explicit ...

Expressivity of quantum neural networks
In this work, we address the question whether a sufficiently deep quantum neural network can approximate a target function as accurate as possible. We start with typical physical situations that the target functions are physical observables, and then we ...
