Utilizing a Standards-Based Toolchain to Model and Execute Quantum Workflows

The increasing availability of quantum devices via the cloud led to a multitude of commercial and scientific tools for developing quantum applications. However, since quantum applications are typically hybrid, comprising both quantum and classical parts, these tools are very heterogeneous. Therefore, combining them within a single application is complicated by incompatible programming languages, data formats, and interfaces. Hence, to enable the development of portable and interoperable quantum applications a standards-based toolchain is required. In this demonstration, we present a holistic toolchain for developing quantum applications utilizing well-established standards for defining workflows, deployment topologies, application interfaces, and provenance data. To demonstrate the practical feasibility of our toolchain, we showcase it for two use cases from the cryptography and machine learning domains.
