Sparse-rank factorization methods in quantum physics

Abstract

Lanczos-based algorithms have been demonstrated to play a pivotal role in quantum computing and classical methods. I review the development of these methods for a variety of physical systems and new implementations. I also review new use cases of these algorithms.
