Atoms under pressure
Zurab Guguchia puts pressure on matter – and in doing so, creates exciting quantum effects such as superconductivity at more easily achievable temperatures.
Electric cars and heat pumps can help the Energy Strategy
In future, flexibly operated heat pumps and electric cars could reduce both electricity imports and electricity prices. That is according to a new study by a Swiss research consortium led by ETH Zurich.
Terbium duet and other quantum art
To create more stable qubits, PSI researchers make terbium ions perform in pairs. Elsewhere, they are using optical tweezers to position atoms with high precision.

The people at PSI
PSI’s cement whisperer
John Provis has dedicated his research career to a building material that is far more exciting than you might think.
Creating circuit diagrams of the brain
Adrian Wanner aims to map the brain’s architecture. Doing this will allow us to better understand neurodegenerative diseases like Alzheimer’s.
With pad, pencil, and algorithms
Physicist Dominik Sidler is developing fundamental theories for previously inexplicable phenomena.
