Quantum Software Design Targets Eleven Distinct User Types

Developers working on quantum software have long struggled with a vague understanding of who their users actually are. According to researchers from the Netherlands, this lack of clarity has led to tools that are either too complex for general users or too simple for specialists. To fix this, a team led by Lukas Schmidbauer has identified eleven distinct user personas, creating a concrete map of the different people who will interact with quantum technology in the coming years.

The goal is to stop treating quantum computing users as a single, monolithic group. Instead, the new framework distinguishes between those who need high-level, user-friendly interfaces and those who require direct access to the underlying hardware. This shift allows software engineers to tailor their products to specific expertise levels, making the technology more accessible without sacrificing the depth needed by advanced researchers.

Mapping Diverse User Needs

Traditionally, knowledge about quantum stakeholders was scattered across different institutions and specialist communities. This fragmentation made it difficult to design software that served everyone effectively. The research team addressed this by gathering insights from expert workshops and interviews, including sessions at the Dagstuhl Seminar in 2024 and the IEEE QCE conference in 2025. These discussions revealed that users have vastly different constraints and preferences regarding how much abstraction they want in their tools.

The resulting personas range from beginners who need simple, guided tools to experts who demand granular control over hardware components. By defining these roles, the team has provided a clear structure for developers to prioritize features. This approach ensures that the software can evolve alongside the hardware, catering to a broader audience beyond just physics specialists.

From Fragmented Insights to Clear Profiles

The process began with identifying five short-term personas during a 2024 focus group. This initial work was expanded with mid-term and long-term profiles derived from the same source. Further qualitative interviews with practitioners in 2025 added nine more distinct profiles, focusing on immediate practical needs. When aggregated, these findings formed the eleven comprehensive user profiles that now guide development efforts.

As reported by GN auto tech/hardware: computing hardware, this detailed profiling represents a significant step forward in the field. It moves the industry away from general design approaches toward targeted tool development. By acknowledging the specific interests and constraints of each group, developers can create more effective resources that accelerate the adoption of quantum computing across multiple disciplines.

Balancing Simplicity With Hardware Access

A key challenge in quantum software design is balancing ease of use with detailed hardware exposure. The new persona framework highlights that this balance is not universal; it depends entirely on the user's role. For some, the value lies in simplicity and accessibility. For others, the value lies in the ability to manipulate low-level parameters. Recognizing this trade-off is essential for creating tools that are both usable and powerful.

While defining user personas might seem abstract given the nascent stage of quantum computing, it provides a strong foundation for practical development. These profiles serve as a guide for creating tailored experiences that were previously unattainable. By moving away from a one-size-fits-all approach, the field can better serve its diverse community, ensuring that the software unlocks the potential of quantum hardware for a wider range of applications.
