Quantum Technologies Collaboration at PSI (QTC@PSI)
A nucleation point of PSI competences towards the quantum technology initiative.
PSI's expertise in the study of quantum matter and engineering of nanoelectronics is directly connected to the availability of world-class large-scale facilities, such as the SINQ neutron and SµS muon source, the SLS synchrotron and the SwissFEL x-ray free-electron laser.
The Quantum Technology Collaboration at PSI (QTC@PSI) serves as a platform to coalesce key competences and know-how (imaging, spectroscopy, sample synthesis, nanofabrication and theory) that will lead to the development of components required to implement quantum technology in everyday life. Critical expertise in nanofabrication, optical amplifiers & microwave technology, metrology, cryogenics & magnet engineering, as well as detector technology exist at PSI today. This combination of scientific excellence in materials science and quantum materials along with the technological know-how and large scale facilities means PSI is uniquely positioned to make significant contributions to the quantum revolution that now is unfolding worldwide.
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.
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 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 new PSI method allows quantum-physical research on materials with the aid of X-ray lasers.
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.
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.
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.
The first experimental observation of three-dimensional magnetic ‘vortex rings’ provides fundamental insight into intricate nanoscale structures inside bulk magnets, and offers fresh perspectives for magnetic devices.
A novel concept for extracting information from spectra where traditional post-processing procedures fail, dubbed ‘software-defined spectroscopy’, offers a fresh approach to high-resolution terahertz spectroscopy. The new method implements an ‘optical comb’ and combines it with a programmable modulator, all using components from the optical internet.
