What is quantum technology?

Our world consists of elementary particles - so-called quanta - which are subject to special physical principles. Bringing these principles into application is already on the way and it is already clear: companies must venture into quantum technology today so that they can keep up with the international competition tomorrow. The background to this is explained by Prof. Dr. Andreas Tünnermann - member of the German Academy of Science and Engineering as well as director of the Fraunhofer Institute for Applied Optics and Precision Engineering IOF and director of the Institute for Applied Physics at Friedrich Schiller University Jena - and Dr. Andreas Böhm - head of the Thinknet Quantum Technology at Bayern Innovativ.

What is quantum technology
Unternehmen müssen heute den Einstieg in die Quantentechnologie wagen, damit sie morgen mit der internationalen Konkurrenz mithalten können.

Prof. Tünnermann, why is quantum technology currently on everyone's lips and why is it so interesting for companies?

Prof. Dr. Andreas Tünnermann: Quantum technologies have a long history . It dates back to the beginning of the last century. Here important phenomena of physics were described by new approaches. Personalities like Schrödinger shaped quantum physics in this time.
The first technical applications of quantum physics happened at the beginning of the 1950s / 60s and they led to the development of microelectronic devices or even the development of the laser.
Today we are facing a revolution in the application of quantum physics. Since a few years we are able to control processes and to use single quanta for questions in the field of sensor technology or also for the transmission of information. This opens up completely new possibilities for us in science, but also in technology. And for companies in particular, it will be important to tap into these added values in the use of quantum technologies and transfer them to markets for sensor technology, information technology or even in the field of imaging.

Andreas, you are building up the quantum technology network at Bayern Innovativ. How do you do that exactly?

Dr. Andreas Böhm: At Bayern Innovativ , we already have numerous industry and technology networks, especially in our fields of specialization ( mobility , Energy , Material , Health , Digitization ), successfully established. Our mission now is to dock quantum technology onto these already existing "classical" networks. This is a direct translation of the idea of technology or knowledge transfer : "What can be done with quantum technology in industries such as automotive, electronics, data processing, and so on. What problems can be solved? At what point can added value be generated?" That is creating awareness of potential applications - on the one hand. Secondly, we would like to build a quantum ecosystem also with partners by helping players from industry to tap into this topic area as potential suppliers of components (electronics, hardware, software) - and here I am thinking primarily of our technologically highly specialized SMEs. This can create a win-win situation for everyone involved.

Prof. Tünnermann, in which industries will quantum technologies be applied?

Prof. Dr. Andreas Tünnermann: There are a number of cross-industry aspects. I think the most important aspect is the topic of security . Indeed, the topic of data sovereignty is a fundamental right in Germany. And by using quantum technologies, we have the chance to make communication of data future-proof - independent of the infrastructure of the provider of the infrastructure, the so-called "provider".
This is where the original advantages of using quantum technology come into play directly. The recipient of a message can detect whether a third party has overheard the message and, for example, whether a key used to encrypt data has been compromised. Another example of what touches me in Jena through its connection to optics is the topic of imaging. Likewise, quantum technologies will allow us to improve sensing, reduce patient radiation exposure in tumor diagnostics and much more.


We are on the verge of a revolution in the application of quantum physics, opening up completely new opportunities for companies. The task now is to tap into and exploit the added value.

Andreas, how does this fit in with the specialization fields of Bayern Innovativ?

Dr. Andreas Böhm: I am picking up directly on Prof. Tünnermann's topic arc: He has already named a concrete application for the topic health or health and medical technology . Likewise, for our other specialization fields Mobility , energy , materials and digitization many possible applications. Topics here are primarily the optimization of complex processes in general, e.g. manufacturing processes, job scheduling or traffic flows, for example. Our goal at Bayern Innovativ is to explain such application examples in an understandable way to potential users in the sense of knowledge transfer, so that they can recognize and ultimately use the potential of quantum technology for themselves.

What would be concrete application examples, Prof. Tünnermann?

Prof. Dr. Andreas Tünnermann: It is important that companies recognize for themselves the individual added value of an application from the field of quantum technology . For example, we have the opportunity to build very efficient and sensitive sensors by controlling quanta, revolutionizing imaging. Similarly, there is the possibility of using quantum computers to analyze logistics problems very quickly, to use combinatorial optimization of a traffic flow in transportation, and many more. These are topics that are just as interesting for the automotive industry as they are for logistics, and ultimately also play an important role in financial companies. This is because added value in security through the use of quantum - for example in the exchange or storage of data - is of great importance, especially in the field of banking.

Andreas, how do you support companies at Bayern Innovativ that want to get started in the field of quantum technology but still have little idea about the subject?

Dr. Andreas Böhm: As explained at the beginning, we are currently building a network in the field of quantum technology . We have many discussions with companies, start-ups and players from research and science who are already active in this topic area or want to be active in the future. To further build our network, we have published a competence map on our homepage. Every company and research institute can register there and present their own services in their profile or start a search call. Thus, we serve as a mediator of cooperation partners. Furthermore, we want to promote through podcasts , specialist articles and publications and events to create awareness for the topic of quantum technology and provide the necessary know-how. We wish that our network grows continuously to take a key position within Bavaria and to further strengthen the Bavarian SMEs.

What message would you / would you like to give our readers on the way?

Prof. Dr. Andreas Tünnermann: My message goes especially to the SMEs: Do not be afraid of quantum technologies! Quantum technologies hold an opportunity. We have been able to show in the past that the innovative power of SMEs helps them to conquer new markets, make them fit for the future and thus also secure jobs in Germany. One prominent example is laser physics. We are now a world leader in this technology, which is a convincing result of quantum technology. Based on this experience, I am firmly convinced that we will succeed, via the innovative SMEs , in bringing quantum technologies from Germany into the world markets as well.

Dr. Andreas Böhm: I would definitely like to endorse Prof. Tünnermann's statements. It is now necessary - in parallel to the research activities - to bring the topic of quantum technology on the road and to generate an economic turnover, so that our Bavarian SMEs continue to play in the forefront of the global economy. Now and in the future!
