A day instead of weeks: testing quantum chips faster – embedded
In the research laboratory in Villach, Infineon has reduced the test time for quantum processors based on ion traps for use in quantum computers from weeks to one day.
The new quantum test laboratory in Villach offers an infrastructure designed for fast test cycles and reliable operation. Here, Infineon, the University of Innsbruck and Joanneum Research are driving joint research into marketable quantum computers. Because there are still some technical challenges to be overcome before a productively usable quantum computer can become a reality. The global research race for the best technology is already in full swing. Among the innovation drivers is a team from Tyrol, Carinthia and Styria. In the “OptoQuant” project, they are jointly researching ion-based quantum processors with integrated optics in order to develop marketable quantum computers.
The quantum particles are caught in the ion trap modules with special cooling and manipulated by laser waves. To this end, Infineon has not only reduced the test time, but now the individual, industrially manufactured quantum chips, which are manufactured using different production methods and surface materials, can also be checked, verified and improved in their chip design more quickly. This accelerated the learning and knowledge transfer within the team.
A test standard was also jointly developed in order to increase the overall quality and reliability of the development process. MATERIALS, the Institute for Surface Technologies and Photonics at Joanneum Research, is developing the quantum processor. »We are working on optical structures to spatially reduce the quantum processor. Together we can decisively develop the heart of future quantum computers,” says Heinz Mayer, Managing Director of Joanneum Research.
Excellent Quantum Triangle
With the new test laboratory in Villach and the semiconductor know-how of Infineon, the quantum expertise of the project partners is successfully supplemented. At the University of Innsbruck, the focus is on basic research, control and software programming. At Joanneum Research in Weiz, the focus is on 3D lithography with integrated optics. »Basic research paved the way for the quantum processor. Now realistic processes and interfaces like the new test laboratory are needed to further develop the quantum processor with industry standards between basic physics and engineering,” says Thomas Monz, senior researcher at the Institute for Experimental Physics at the University of Innsbruck.
The partnership is also an important hub for the next generation of quantum researchers. Ten students are currently working on their scientific projects at Infineon in Villach alone. You will be supervised by four quantum experts. Two quantum jobs at Infineon are currently still to be filled. Quantum research started at Infineon Austria in 2016. Since 2020 it has been assigned to the Power & Sensor Systems DCDC business line.
Forward-looking quantum lighthouse projects need appropriate framework conditions. »When companies initially invest in future technologies and score points with innovative products ‘Made in Austria’, then this is of enormous importance for Austria as a business location. Therefore, we are particularly pleased when we as FFG can support Infineon’s new quantum test laboratory via the R&D project ‘OptoQuant’,” explains Henrietta Egerth, Managing Director of FFG. With its European network, the FFG also enables the strengthening of transnational cooperation for this important future and key technology.
promising applications
Quantum computers have the potential to solve certain complex and computationally intensive tasks many times faster than classic computers. For example, highly complex processes in logistics or energy supply could be quickly optimized and contribute to robust supply chains. There is also great potential in the development of new drugs, vaccines or personalized medicine in order to be able to simulate effects and side effects more quickly. A lot is also possible in the development of completely new, environmentally friendly, lighter materials.
Research project »OptoQuant«
The quantum test laboratory is being implemented as part of the »OptoQuant« project, which is scheduled to run for three years. It started in June 2021 and will run until 2024. The research volume totals 2.7 million euros and is co-financed by the “Quantum Research and Technology” initiative of the National Foundation for Research, Technology and Development and the Austrian research promotion agency FFG.
