This talk will give updates on achievements and extensions of project PlanQK (Platform and Ecosystem for Quantum-assisted Artificial Intelligence), funded by Federal Ministry for Economic Affairs and Energy. Furthermore, we will present novel research results, including - Insights on Training Neural Networks for QUBO Tasks - Approximating Archetypal Analysis Using Quantum Annealing - A Quantum Annealing Algorithm for Finding Pure Nash Equilibria in Graphical Games - Approximate Approximation on a Quantum Annealer
