Using Open API for the Development of Hybrid Classical-Quantum Services

Quantum Computing has started to demonstrate its first practical applications. As the technology develops to a point of maturity that allows quantum computers to expand commercially, large companies such as Google, Microsoft, IBM and Amazon are making a considerably effort to make them accessible through the cloud so that research and industry initiatives can test their capabilities. The characteristics of this paradigm and the lack of mature tools still make the process of defining, implementing, and running quantum, or hybrid classical-quantum software systems difficult compared with the procedures used for pure classical ones. To address this lack, we present a demonstration of a method for defining quantum services and the automatic generation of the corresponding source code through an extension of the Open API Specification. In this demo we present an extension that enables developers to define quantum services with a high abstraction level, link them with quantum circuits, and generate the source code of the service to be deployed in a quantum computer in the same way they do for classical services.
