Boosted with superconductivity: Semiconductor technology can get a new twist by exploiting quantum effects in superconductors.
Exploring the practical benefits of exotic materials
Niels Schröter receives an award from the Swiss Physical Society (SPG).
Quantum billiards with correlated electrons
Our collaborators at the Jozef Stefan Institute – the leading author, Jan Ravnik, is now a PSI Fellow at LMN – report a study of the electron ordering in equilateral triangle structures via photoexcitation of the prototypical dichalcogenide 1T-TaS2.
"The goal is an experimental quantum computer in the canton of Aargau"
ETH Zurich and PSI are jointly opening a Quantum Computing Hub. An interview with Gabriel Aeppli and Christian Rüegg about the new research centre.
ETH Zurich and PSI found Quantum Computing Hub
ETH Zurich and the Paul Scherrer Institute PSI are opening a joint centre for the development of quantum computers. The aim is to advance the realisation of quantum computers based on both ion traps and superconducting devices.
A time-domain phase diagram of metastable quantum states
Our collaborators at the Jozef Stefan Institute – the leading author, Jan Ravnik, is now a PSI Fellow at LMN – report a ‘dynamical’ phase diagram of metastable quantum states generated via photoexcitation of the prototypical dichalcogenide material 1T-TaS2.
Water and quantum magnets share critical physics
At high pressure, liquid water and water vapour merge together – the phase boundary disappears. Researchers have now discovered a similar behaviour in a quantum magnet.
New blueprint for more stable quantum computers
PSI researchers have shown how faster and better defined quantum bits can be created. The central elements are magnetic atoms from the class of so-called rare-earth metals, selectively implanted into the crystal lattice of a material.
Scientists develop a new kind of qubit based on the concept of Schrödinger’s cat
Scientists in the Applied Physics department of Yale University – one of the leading authors, Alexander Grimm, has in the meantime relocated to PSI – have developed a new device that combines the Schrödinger’s cat concept of superposition (a physical system existing in two states at once) with the ability to fix some of the trickiest errors in a quantum computation.
First demonstration of a Germanium laser
Scientist at the Paul Scherrer Institut and ETH Zürich, with colleagues from CEA Grenoble, have demonstrated and characterized a technology that, for the first time, yields lasing from strained elemental Germanium. This achievement underlines PSI’s leading role in the development of Silicon-compatible laser light sources.
Now it's time for something new
If you make electronic components smaller, they unfortunately get hotter. Also, we will soon reach the limit of technically feasible miniaturisation. At PSI, Gabriel Aeppli and Christian Rüegg are working on fundamentally new, physical solutions for better computers and data storage devices.
