Exploration by Maximizing Renyi Entropy for Reward-Free RL Framework
AAAI Conference on Artificial Intelligence, 2020 Exploration is essential for reinforcement learning (RL). To face the challenges of exploration, we consider a reward-free RL framework that completely separates exploration from exploitation and brings new challenges for exploration algorithms.

Experimental Detection of the Correlation Rényi Entropy in the Central Spin Model. [PDF]
Physical Review Letters, 2020 We propose and experimentally measure an entropy that quantifies the volume of correlations among qubits. The experiment is carried out on a nearly isolated quantum system composed of a central spin coupled and initially uncorrelated with 15 other spins.

Page curves and typical entanglement in linear optics [PDF]
Quantum, 2023 Bosonic Gaussian states are a special class of quantum states in an infinite dimensional Hilbert space that are relevant to universal continuous-variable quantum computation as well as to near-term quantum sampling tasks such as Gaussian Boson Sampling ...

Note on entropy dynamics in the Brownian SYK model
Journal of High Energy Physics, 2021 We study the time evolution of Rényi entropy in a system of two coupled Brownian SYK clusters evolving from an initial product state. The Rényi entropy of one cluster grows linearly and then saturates to the coarse grained entropy.

Renyi entropy of chaotic eigenstates. [PDF]
Physical Review E, 2017 Using arguments built on ergodicity, we derive an analytical expression for the Renyi entanglement entropies which, we conjecture, applies to the finite-energy density eigenstates of chaotic many-body Hamiltonians.

Green's function approach to entanglement entropy on lattices and fuzzy spaces
Physics Letters B, 2019 We develop a Green's function approach to compute Rényi entanglement entropy on lattices and fuzzy spaces. The Rényi entropy resulting from tracing out an arbitrary collection of subsets of coupled harmonic oscillators is written as zero temperature ...

Journal of Inequalities and Applications, 2023 In this paper, four new Green functions are used to generalize Levinson-type inequalities for the class of 3-convex functions. The f-divergence, Renyi entropy, Renyi divergence, Shannon entropy, and the Zipf–Mandelbrot law are also used to apply the main

Lower and upper bounds for entanglement of Rényi-α entropy
Scientific Reports, 2016 Entanglement Rényi-α entropy is an entanglement measure. It reduces to the standard entanglement of formation when α tends to 1. We derive analytical lower and upper bounds for the entanglement Rényi-α entropy of arbitrary dimensional bipartite quantum ...

Entropy linear response theory with non-Markovian bath
Journal of High Energy Physics, 2021 We developed a perturbative calculation for entropy dynamics, which considers a sudden coupling between a system and a bath. The theory we developed can work in a general environment without Markovian approximation.
