Simula to Lead Quantum Software Testing for EU Q-VERSE
Simula Research Laboratory will lead software testing and integration for Q-VERSE, an EU-funded project. Specifically, Q-VERSE aims to develop tools that enable quantum applications to operate across various hardware platforms, preventing vendor lock-in for developers.
This 36-month initiative unites Simula with 12 partner organizations from six European countries This project is particularly noteworthy because quantum software tooling has lagged behind hardware development, and Europe is investing in shared, vendor-neutral infrastructure to bridge this gap.
Simula’s Role
Indeed, Simula will head Q-VERSE Work Package 4, titled “Quantum Enablers and Integration Components.” The team is led by Dr. Shaukat Ali, Head of Department for Engineering Complex Software Systems, and Dr. Paolo Arcaini, Chief Research Scientist. Their responsibilities include coordinating quantum and classical machines, identifying bugs in probabilistic outputs, and measuring performance over time.
Simula’s stated deliverables include:
- Hybrid quantum-classical workflows that divide tasks between standard computers and quantum processors, utilizing Graph Neural Networks and Reinforcement Learning for task allocation.
- An automated testing framework to detect software flaws, along with machine learning tools to filter out hardware noise.
- A benchmarking system to monitor real-time performance of quantum applications and identify slowdowns or hardware degradation.
“Quantum hardware is evolving rapidly, but software tools have lagged behind,” stated Dr. Ali in the announcement. He emphasized the goal of applying software engineering principles to enable developers to build reliable, production-ready quantum applications.
The development of reusable, open software components is emerging as a distinct area of focus. Fujitsu recently open-sourced a quantum application package designed to provide developers with shared building blocks. Such components require the kind of testing and integration that Q-VERSE provides.
Project Scope and Challenges in Testing
Q-VERSE is part of the European Quantum Flagship, the EU’s decade-long initiative to establish Europe as a leader in quantum technology. The project receives funding from the Horizon Europe program, as detailed on Simula’s project page. The developed tools will be validated through five industrial use cases, including railway scheduling, financial portfolio optimization, drug design, and telecommunications data analytics.
The official materials do not disclose the exact budget, grant agreement number, or the complete list of 12 partners. Furthermore, the specific frameworks, simulators, and hardware targets that Simula will test against have not yet been named.
Testing quantum software presents unique challenges due to the probabilistic nature of outputs, which means an incorrect result may not always appear as a clear bug. The complexity is further amplified in cross-border consortiums where partners utilize diverse hardware in different countries, making validation even more difficult. Addressing these challenges is the core mission of Q-VERSE over the next three years.
