Germany’s first cryogenic measuring setup for statistical quality measurement of qubit devices on whole 200- and 300-mm wafers has started operation at Fraunhofer IAF. The on-wafer prober can characterize devices based on semiconductor quantum dots and quantum wells as well as superconductors at measurement temperatures below 2 K. Fully automated operation will allow researchers to build up a quantitatively relevant database and advance the industrial production of high-quality devices for quantum computing and quantum sensing in Europe.

Bidirectional charging enables electric vehicles to be both charged and discharged as needed. E-cars can thus serve as mobile electricity storage units and contribute to increasing the flexibility of the energy system. To ensure that bidirectional charging can be used on a broad scale, a consortium led by Fraunhofer IAF is researching innovative charging technologies: In the recently launched project GaN4EmoBiL, the partners are developing new semiconductor, device and system technologies for the 800 V class.

In the Fraunhofer lighthouse project ElKaWe, researchers are working on the development of electrocaloric heat pumps as an alternative to the currently prevailing compressor technology. These new types of heat pumps promise higher efficiency and do not require refrigerants. Researchers at Fraunhofer IAF have now reached a milestone in power electronics: They have realized an ultra-efficient circuit topology for voltage converters with over 99.74 percent electrical efficiency. This result is a worldwide benchmark and an important step on the way to more efficient solid-state heat pumps.

Microscopic imaging of magnetic fields, enabled by quantum sensing, allows the measurement of the unique magnetic fingerprint of objects. This opens the door for fundamentally new applications in various fields such as materials testing or biomedicine. Fraunhofer IAF has developed an innovative method using fast camera images in the form of an improved wide-field magnetometer. The system offers a unique compromise of sensitivity, resolution and speed. It will be presented at LASER World of QUANTUM 2023 as part of the Quantum Sensing Hub Freiburg, in which the institutes Fraunhofer IAF, IPM and IWM pool their expertise in the field of quantum magnetometry.
