Variational Quantum Algorithms – Origin, Potentials, and Problem

Today’s quantum computers are noisy, i.e. only algorithms that spent a short amount of time can be successfully executed. This can be achieved by hybrid algorithms that split their work between a classical computer and a CPU. In this talk we focus on the often used subcategory of variational quantum algorithms, describe their principles and sketch the workhorses VQE and QAOA. The promising technique of warm starting algorithms and their origin are described. Problems and potentials are scratched to show lots of research opportunities in this domain.

Please note that the talk will be in German!
