Lean-Quantum library formalizes quantum information theory with AI assistance

Researchers have developed a new Lean 4 library called Lean-Quantum, designed to aid in the formalization of quantum information theory. This library provides a robust, basis-independent framework for finite-dimensional quantum mechanics, compatible with Mathlib. A key demonstration of its capabilities is the formalization of the data processing inequality (DPI) for the sandwiched Rényi relative entropy, a fundamental result in quantum information. The project aims to offer machine-checkable foundations for future AI-assisted research in the field. AI
