When large amounts of money are invested in the research of small things, it is because our leaders firmly believe that our society and economic future can be shaped this way. These “small things” mean the objects and phenomena of the quantum world. Science is increasingly succeeding in taking control of this world. The range of topics spans from quantum communication with its inherent secure data transmission to quantum computers for unimagined processing power and to quantum simulations of chemical reactions and quantum sensors for medical diagnostics. Great technological promise with enormous economic potential is popping up in these fields. This potential is being raised on a large scale by the European Commission’s levied billion euro “Quantum Technologies Flagship” funding program and beyond that, it’s being pushed forward in flanking national funding programs. At the same time, not only large companies with long traditions, but also young start-ups are pushing developments which will bring entirely new products to the market which are based on quantum technology (QT).

 

Just as PTB was once – thanks to its measuring skills – at the beginning of quantum mechanics, PTB is now driving the second quantum revolution’s wave of metrological possibilities – with the next generations of atomic clocks, even more precise electrical standards and innovative measurement capabilities in medicine. At the same time, the metrological fundamental research leads to technological applications. To make these applications available for the economic development of QT, the Quantum Technology Competence Center (QTZ) was recently founded.

Besonders in Hochrisikobereichen wie der Medizin muss Künstliche Intelligenz (KI) sicher und verlässlich sein: Es sollte nachvollziehbar sein, nach welchen Kriterien die KI ihre Entscheidungen trifft, und man braucht objektive Prüfverfahren für die Zulassung von Medizinprodukten mit KI. Als neutrale Institution und oberste Instanz für genaueste Messungen will die Physikalisch-Technische...

If you think of passing hours, minutes and seconds when you imagine a clock, you’re not wrong, but not completely right, either. When clocks measure time very accurately, scientists can do much more than just state the time:

While homo sapiens may not be able to detect magnetic fields, as “homo technicus”, human beings make use of a wide variety of technical sensors. Quantum effects are increasingly being exploited to collect information unavailable by conventional means – for example, in order to detect magnetic fields in living organisms or to use such fields for medical imaging purposes.

The discovery that the world is governed by principles of quantum mechanics is over 100 years old. Today, we take many technological applications of quantum physics for granted – from lasers and semiconductor technology to magnetic resonance imaging (MRI). The applications of second-generation quantum technology currently emerging go a step further, allowing individual quantum objects to be controlled and deliberately exploiting basic quantum effects for technological innovations in the near and distant future.

Historically speaking, not much time has passed since Nicola Tesla dazzled audiences with his controlled bursts of lightning and ghostly seeming light effects and a certain Thomas Alva Edison electrified the industrialized world with his inventions. The discovery and technical utilization of electricity took off at the end of the 19th century and conquered more and more conventional technical terrain until, in the late 1940s, the transistor was invented at Bell Labs in New Jersey. The transistor gave electricity its first quantum-mechanical form.

Information is the most important resource of our time. Enormous amounts of data are collected, processed in computers and exchanged via glass fibers, the air and satellites. We are caught up in information flows that never break and that race around the length and breadth of the globe at the speed of light. Much of this data has to be exchanged between the sender and the receiver in a safe way, as not everything that is communicated is allowed or supposed to be in the public eye. This includes patients’ data in the field of medicine as well as financial data that is communicated with and between banks and highly sensitive data from the fields of politics and the economy. Forms of communication that are protected from unauthorized access are necessary for all these data transfers.

Only very few people have so far become accustomed to the phenomena of the quantum world. Yet the technologies that come out of this world are to be used by everyone. PTB is therefore specifically expanding its fundamental research and its highly specialized services to include a Quantum Technology Competence Center (QTZ) that focusses on applications. Work on setting up this center began in 2019, and the QTZ is going to form an important basis for industrial developments of quantum technologies. Special focus will be placed on start-ups as well as on small and medium-sized enterprises (SMEs).
