A European quantum-technology study has found that 12.9% of the 195 signals it examined had reached operational level, while most remained at proof-of-concept or system-demonstration stages. The findings point to uneven maturity across potential applications, rather than a technology landscape that is uniformly ready for deployment.
The percentage has a specific scope: it describes the signals detected and assessed in a foresight exercise. It is not a measure of the proportion of all quantum technologies, businesses or commercial installations that are operational. That distinction matters when interpreting what the figure says about the technology’s readiness.
Nearly half of the detected signals were at proof of concept, and almost one third were at system demonstration. Together, those findings place much of the activity examined before the operational stage. They also underline why evidence of progress in one application should not be treated as evidence of equivalent maturity across the wider field.
Different applications, different stages
The study considers quantum sensing, communication and computing across twelve themes. Potential uses include cybersecurity, climate science, health, energy, transport, sensing and communications. These are areas of possible application, not a list of sectors in which quantum technology has already achieved widespread use or delivered established benefits.
The breadth of those possibilities is part of the policy challenge. A single headline figure cannot capture the different stages reached by the applications examined. The study’s findings instead support a differentiated approach, with attention to whether a technology is still being explored, demonstrated as a system or considered for commercial rollout.
The operational share therefore needs to be read alongside the much larger proportions at earlier stages. It establishes that some of the detected signals have progressed further than others, but it does not establish the scale of their commercial deployment. Nor does the sample provide a comprehensive census of the quantum sector.
Policy beyond a single measure of readiness
The recommendations distinguish between support for early pilots, test beds and commercial rollout. Those categories reflect the uneven maturity identified in the analysis. Rather than treating every potential application as ready for the same form of support, the proposed approach recognises that needs differ at different stages of development.
Investment in literacy, shared infrastructure, standards and industrial capacity is also recommended. These are policy priorities identified by the study, not announcements that investment has been committed or that new facilities and standards have been delivered. The emphasis extends beyond individual technologies to the wider conditions needed for their assessment and use.
Evaluation, validation and deployment frameworks feature in the findings. The distinction is important: identifying a promising application or demonstrating a system is not the same as establishing how it can be evaluated, certified and integrated. The study places those capabilities within the question of Europe’s longer-term competitiveness.
Europe’s position
The study finds that Europe hosts nearly one third of quantum companies. That gives a separate indication of the region’s place in the sector, but it should not be confused with the maturity measure. The company share and the operational share describe different things and cannot be used interchangeably.
Europe’s longer-term position is presented as dependent on its ability to evaluate, certify and integrate quantum technology. The findings do not offer a guarantee of future competitiveness. They identify capabilities that matter alongside the presence of companies and the progress of individual applications.
The central picture is one of partial operational readiness within a wider field still dominated, in this sample, by proof-of-concept and demonstration activity. The study identifies both potential uses and policy needs, while leaving a clear boundary around its main statistic: 12.9% applies to the 195 detected signals, not to quantum technology as a whole.
