QSOA®: Dynamic integration for hybrid quantum/Classical software systems

Abstract

This is the “quantum decade” when quantum computers are proving to be more useful for some types of processing than their classical counterparts. The solutions of the future will combine classical IT with quantum algorithms and applications. However, there is very little work that addresses this issue. Each manufacturer provides specific tools for their products, which makes integration between quantum and classical systems a costly and time-consuming process.We believe that we should follow good software engineering principles and best practices to build platforms and tools that insulate software and systems engineers from implementation details and provide them with adequate support. In this paper we propose qSOA® as a mechanism for the dynamic integration of hybrid (quantum/classical) software systems and present in detail an SDK for Python. qSOA® provides a set of well-defined functions with which a classical system can access quantum products as if they were a piece of classical software, accessing the use case and not its complexities. In addition to some examples that illustrates its operation in real cases, we present the evaluation of qSOA® by 200 quantum software developers in a workshop in collaboration with AWS Braket.
