Title: Quantum theory of graphs and networks
Duration: 01/07/2015 - 28/06/2019
Principal Investigator: doc. Mário Ziman, PhD

Project Annotation: This project is focused on design of effective quantum algorithms, development of quantum-chemistry simulations and distributed quantum-information innovations. All the particular tasks have in commont he concept of quantum network representing complex quantum systems and their topological relations. The network exhibits interactions (in broader sense) and/or correlations between individual quantum systems. Our particular goals within this project are divided into three logical workpackages corresponding to aforementioned research areas: quantum walks and computation, tensor network states and kinematics and dynamics of quantum networks.
