Abstract
Hybrid quantum-classical applications are often implemented as monolithic applications that comprise various tightly-coupled classical and quantum tasks. However, the lifecycle of such applications can benefit from using service-oriented architectures, as they simplify scalable and resilient deployments and improve development processes by decoupling complex processes into more comprehensible work packages. In this demonstration, we (i) introduce Quokka, a service ecosystem that facilitates workflow-based development and execution of quantum applications by providing dedicated services for implementing each task in variational quantum algorithms. Further, (ii) we show how it can be used to orchestrate an example quantum application using workflows.
