Quantum Circuits for the Metropolis-Hastings Algorithm
Baptiste Claudon, Pablo Rodenas-Ruiz, Jean-Philip Piquemal +1
Szegedy's quantization of a reversible Markov chain provides a quantum walk whose spectral gap is quadratically larger than that of the classical walk. Quantum computers are theref…

Quantum Solvers for Nonlinear Matrix Equations in Quantum Chemistry
Pablo Rodenas-Ruiz, Andrew Zhao, Joonho Lee
We present a quantum algorithm for solving algebraic Riccati equations, with applications to quantum-chemical random-phase approximation (RPA) and higher-order RPA theories. Our me…

MM-HSD: Multi-Modal Hate Speech Detection in Videos
Berta Céspedes-Sarrias, Carlos Collado-Capell, Pablo Rodenas-Ruiz +2
While hate speech detection (HSD) has been extensively studied in text, existing multi-modal approaches remain limited, particularly in videos. As modalities are not always individ…
