Generalized Rényi Entropy Accumulation Theorem and Quantum Probability Estimation

Learn about groundbreaking advancements in quantum cryptography through this conference talk that introduces a new entropy-accumulation bound for enhanced security analysis of device-dependent and device-independent cryptography protocols. Explore how this innovative approach addresses previous limitations by delivering improved finite-size performance and enabling computation through convex optimization without requiring affine min-tradeoff functions. Discover the connection between entropy accumulation and quantum probability estimation, leading to fully-Rényi security proofs. Presented at the 19th Conference on the Theory of Quantum Computation, Communication and Cryptography (TQC 2024) at OIST, Japan, this 20-minute presentation delves into theoretical quantum information science and its practical applications in cryptographic security.
