Exploring band structure of crystals using variational quantum algorithms

Abstract:
The electronic band structure of a solid describes the range of energy levels that electrons can occupy. Although the information it provides is valuable for research, electronic structure calculations rank among the most computationally intensive tasks. The usage of quantum algorithms might be a remedy to this problem and is being actively researched among the quantum computing community. In this seminar, we will talk about variational quantum algorithms and how they can be implemented to solve simple electronic structure problems. We will explore the possibilities and problems of this approach based on the custom Python library BandCalQ written using Qiskit SDK.
