Industrial users of cloud-based quantum computing need to assess the capabilities and advantages of different quantum systems for various application areas. There are many metrics that are difficult or impossible to distinguish, especially for end-users. By defining requirements and criteria for the evaluation of different quantum computers, quantum algorithms and their implementation, Fraunhofer FOKUS as applied research partner contributes essentially together with QBN to the development of a strong quantum computing industry and helps end-users to navigate in this promising and dynamic technology field.

The core metrics are to be defined in a way that they describe the properties of a QPU (Quantum Processing Unit) with precise benchmarks and can assess the QPU performance in various relevant applications. These applications then no longer have to be tested separately, but can be assessed on the basis of the KPIs, which manufacturers and users can measure in a fair and reproducible manner. The DIN SPEC will then serve as a basis for European and international standards on KPIs to benchmark quantum computers.
