Bettina Heim won the Swiss figure-skating championships before developing an interest in quantum computing. She studied physics at ETH and now develops software for the computers of the future.
Between crystals, cats and quantum

Researchers at ETH Zurich have shown that quantum states of single electron spins can be controlled by currents of electrons whose spins are evenly aligned. In the future, this method could be used in electronic circuit elements.
A plunge into universality

Recent research carried out in the Institute for Theoretical Physics investigated universal scaling in non-homogeneous lattice systems.
Solving physics puzzles with coloured dots

By analysing images made of coloured dots created by quantum simulators, ETH researchers have studied a special kind of magnetism. In the future this method could also be used to solve other physics puzzles, for instance in superconductivity.

Researchers at ETH Zurich have studied topological effects in an artificial solid, making surprising observations. The new insights into topological pumping could be used for quantum technologies in the future.

Marina Marinkovic works to understand more about the strong force that binds quarks and gluons into hadrons as described by quantum chromodynamics.
A new ion trap for larger quantum computers

Researchers at ETH have managed to trap ions using static electric and magnetic fields and to perform quantum operations on them. In the future such traps could be used to realize quantum computers with far more quantum bits than have been possible up to now.
How to make bright quantum dots even brighter
![Illustration of the cube-shaped perovskite nanocrystal and the molecules that form around it.](https://ethz.ch/en/news-and-events/eth-news/news/2024/01/how-to-make-bright-quantum-dots-even-brighter/_jcr_content/pageimages/imageSmall.imageformat.contentteaser.1410624913.jpg)
Researchers at Empa and ETH Zurich have developed methods for making perovskite quantum dots faster and more efficient emitters, thereby significantly improving their brightness. This is relevant for applications in displays as well as in quantum technologies.
Quantum scars as a way out of thermalisation
