Abstract: In the mathematical framework, quantum states are represented as density matrices, i.e., positive semi-definite matrices with trace one, and quantum operations are represented as trace preserving completely positive linear maps. In quantum information science, one often has to estimate various measures between different quantum states and quantum processes. One also needs to design quantum operations with special properties. These give rise to many optimization problems involving matrices and linear transformations. In this lecture, selected results, techniques, and open problems in this line of study will be described.
