Superconductivity offers new insights into quantum material
For the first time since the discovery of the material MnBi2Te4 (MBT), researchers at the University of Twente have successfully made it behave like a superconductor. This marks an important step in understanding MBT and is significant for future technologies, such as new methods of information processing and quantum computing.

Smarter incentives prevent grid congestion
Doctoral students Bart van der Holst and Gijs Verhoeven investigated financial measures for grid operators to make better use of the existing grid capacity. Our electricity grid cannot keep up with the energy transition. New schools, businesses and neighborhoods have to wait for a connection and solar panels are already switched off at peak times.

Freezing electronics to control diamond spin qubits
Researchers from Fujitsu and QuTech have developed new and ultra-cold electronic circuits to control diamond-based quantum bits. As a result of their joint research project, it becomes possible to build larger quantum computers, through overcoming the 'wiring bottleneck', while maintaining high quality performance.

Preventing power quality issues caused by electric vehicle charging
Along with ElaadNL, PhD researcher Tim Slangen studied the phenomenon known as supraharmonic disturbances, which can adversely affect the operation and efficiency of electrical appliances. With the growing and obvious concerns about climate change, the transition from fossil to renewable energy is accelerating.

Creating efficient transparent p-type conductors
Transparent conductors are essential for many devices, such as touch screens and solar cells. Copper iodide (CuI) can conduct electricity while staying see-through but is not as good as some other materials. Researchers from the University of Twente managed to improve the conductivity of CuI while keeping 75% of its transparency.

Measuring 5G antennas in the reverberation chamber
Anouk Hubrechsen defended her PhD thesis cum laude at the Department of Electrical Engineering on October 26th. We are using ever more (smart) devices connected to the 5G network. The high-frequency antennas they contain are often integrated with chips, and this adds a layer of complexity to testing.

Controlling waves in magnets with superconductors for the first time
Quantum physicists at Delft University of Technology have shown that it's possible to control and manipulate spin waves on a chip using superconductors for the first time. These tiny waves in magnets may offer an alternative to electronics in the future, interesting for energy-efficient information technology or connecting pieces in a quantum computer, for example.

First evidence for new superconducting state in Ising superconductor
In a ground-breaking experiment, scientists from the University of Groningen, together with colleagues from HFML-FELIX, University of Twente and the Harbin Institute of Technology (China), have discovered the existence of a superconductive state that was first predicted in 2017. In this week's edition of Nature, they present evidence for a special variant of the so-called FFLO superconducting state, a discovery that could have significant applications, particularly in the field of superconducting electronics.

New material paves the way for more efficient electronics
Researchers from the University of Twente proved that germanene, a two-dimensional material made of germanium atoms, behaves as a topological insulator. It is the first 2D topological insulator that consists of a single element. It also has the unique ability to switch between 'on' and 'off' states, comparable to transistors.

Confining classical and quantum waves with crystals
Manipulating elusive waves like light, sound or electrons, in periodic structures or crystals, has something mysterious. In the leading physics journal Physical Review Letters, published by the American Physical Society, a team of researchers from the University of Twente now describes how any kind of wave, whether quantum or classical, is confined in any kind of crystal.

Interplay of electronics and photonics for next generation quantum devices
For building quantum computers, making use of both electronics and photonics - technology that works with light - on one and the same chip, is promising. Thanks to silicon technology that we know well from today's electronic devices, quantum devices could be better protected from influences from the outside world.
