Prof. Dr. Dr. h.c. Frank Leymann, Dr. Johanna Barzen & Benjamin Weder: “Hybrid Quantum Applications”

Non-trivial quantum applications are almost always hybrid, i.e. they consist of both quantum and classical parts. Prof. Dr. Frank Leymann, Dr. Johanna Barzen and Benjamin Weder show that two orchestration technologies are helpful for such applications, namely workflow technology and provisioning technology and how these technologies have to interact. The principle is demonstrated using the Camunda Platform and OpenTOSCA. The connection with the new IBM QisKit Runtime is clarified. As a use case of hybrid applications, the prototype tool QHAna is presented, which allows to compare traditional implementations and quantum implementations of ML algorithms in the domain of film sciences.
