Abstract: The execution of quantum algorithms typically requires classical pre- and post-processing, making quantum applications inherently hybrid. Classical resources are of particular importance for so-called variational quantum algorithms, as they leverage classical computational power to overcome the limitations imposed by today’s noisy quantum devices. However, the additional complex tasks required by these algorithms, complicate the challenge of integrating quantum circuit executions with classical programs. To overcome this challenge, we leverage the advantages and versatility of workflows, and introduce a workflow modeling extension for orchestrating variational quantum algorithms. The modeling extension comprises new task types, data objects, and a comprehensible graphical notation. Furthermore, we ensure interoperability and portability by providing a method for transforming all new modeling constructs to native modeling constructs, and showcase the practical feasibility of our model ing extension by presenting a system architecture, prototype, and case study.
