QuantumX: an experience for the consolidation of Quantum Computing and Quantum Software Engineering as an emerging discipline

A coalition of 22 researchers from leading Spanish institutions has formally launched QuantumX, a dedicated conference track within the XXIX JISBD 2025, to establish Quantum Software Engineering (QSE) as a recognized discipline. The event, documented in a 16-page arXiv paper (2603.10621), served as a pioneering forum to adapt classical software engineering principles—like quality, governance, testing, and abstraction—to the unique challenges of quantum computing. Presented works spanned critical areas including quantum service engineering, hybrid classical-quantum architectures, formal quality models, circuit optimization techniques, and quantum machine learning, reflecting the field's interdisciplinary nature and growing technical maturity.

Beyond presenting research, QuantumX focused on community building, fostering collaboration through national and Ibero-American networks like RIPAISC and QSpain. The track included dedicated networking sessions that encouraged joint initiatives and long-term partnerships. The resulting article provides a structured synthesis of the contributions, identifies common engineering concerns, and outlines a clear set of open challenges for QSE's future. This foundational effort successfully positions Spain as an emerging, organized contributor within the European and global quantum software ecosystem, moving the field from isolated research to a coordinated engineering discipline.
