Bosch Quantum Sensing: Turning Research into Commercial Products

Quantum technologies are regarded as a key technology for the coming years – but where do we really stand on the path to industrial application? Which areas of application are particularly promising, and what is needed to turn technological potential into economic reality? Dr Katrin Kobe, CEO of Bosch Quantum Sensing, hosting partner of Quantum Effects, discusses this.

Quantum technologies are still a topic for the future, though intensive work is already underway in many quarters. Where do you currently see the greatest progress on the path from research to industrial application?

Of all quantum technologies, quantum sensing is the most market-ready. We are seeing increasingly higher levels of technological maturity, as well as a greater focus on transferring laboratory set-ups to real-world operating environments. Many developments are currently moving from research towards market-ready products.

Bosch Quantum Sensing is specifically driving the commercialisation of quantum sensors based on so-called NV centers (nitrogen-vacancy centers) in diamond. A key advance in this regard is the miniaturisation of the technology: we have succeeded in miniaturising highly sensitive quantum sensor prototypes to the point where they are compact and robust enough for practical use. In doing so, we have created an essential prerequisite for deploying the technology in industrial applications.

Which areas of application are currently generating the most momentum in the industry – and why are sectors such as medical technology receiving so much attention?

NV technology offers a unique combination of advantages that are attractive to numerous sectors. Potential applications include medical technology, mobility, industrial manufacturing and subsurface exploration.

In the long term, quantum sensors could also enable applications in the field of brain-computer interfaces, where devices are controlled directly via brain signals.

There are several reasons why medical technology is mentioned so frequently: a number of developments are converging here – an ageing population, the rising global incidence of cardiovascular diseases, and the growing need for earlier, more precise and, where possible, non-invasive diagnostics. Quantum sensors have the potential to open up new possibilities in this area.

In your view, what are the greatest advantages of quantum sensor technology over existing technologies – and where is the limit beyond which conventional technologies remain the better choice?

Compared with conventional sensors, quantum sensors offer, in particular, significantly higher sensitivity. They enable higher spatial resolution and a wider measurement range. This allows them to perform measurement tasks that were previously impossible or only possible to a limited extent with conventional technologies, thereby opening up entirely new applications.

However, conventional sensors will remain the better choice in areas where the performance of current technologies is already sufficient. Quantum sensors will therefore not replace classical technologies, but rather complement them in areas where they can demonstrate their exceptional properties, for example in terms of sensitivity.

As an industrial company, how do you recognise when a future-oriented topic is becoming a strategically relevant business area?

For us, three factors are particularly crucial: the concrete benefits for future customers and users, the cost-effectiveness of the solution, and sufficient technological maturity. We see great potential in quantum sensor technology – ranging from industrial applications right through to the consumer sector.

We are convinced that quantum sensor technology can improve people’s lives whilst also offering attractive market opportunities. For an industrial company, a future-oriented topic becomes a strategically relevant business area when technology, the market and economic viability come together.

Baden-Württemberg regards itself as a hub for innovation in future technologies. Where do you currently see the region in terms of quantum sensor technology in a national and European context – and what needs to happen for its technological strength to translate into economic leadership?

Baden-Württemberg and Germany are among the world’s leading centres in the field of NV quantum sensing. This is evident from the presence of several leading companies as well as internationally renowned universities and research institutions.

The key now is to translate this technological strength into economic value creation. A deep-tech field such as quantum sensor technology requires staying power and a strong ecosystem comprising research, industry, start-ups, investors and policymakers. A concerted approach by all stakeholders is of central importance here.

At the same time, appropriate investment is required, as the path from research to industrial-scale production is long. The entire value chain must be established and further developed for commercialisation. From a policy perspective, technological sovereignty also plays an important role – particularly with regard to critical materials and resilient supply chains.

Many companies are watching quantum technologies with great interest, but are still hesitant to get involved. What advice would you give to industrial users today?

In my view, early testing is the best way to explore the possibilities and potential areas of application within one’s own company. Companies can gain practical experience and develop an understanding of the technology. At the same time, they can trial initial applications and secure early access to a new key technology.
