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.

First experimental observation of new type of entanglement in a 2D quantum material

Scientists from PSI and the École polytechnique fédérale de Lausanne (EPFL) have shown experimentally, for the first time, a quantum phase transition in strontium copper borate, the only material to date that realizes the famous Shastry–Sutherland quantum many-body model.

First direct look at how electrons ‘dance’ with vibrating atoms

Highly precise measurements of iron selenide show how electrons move in sync with atomic vibrations rippling through the quantum material. The experiments were carried out at the LCLS x-ray free-electron laser of the SLAC National Accelerator Laboratory and at Stanford University by a team including Quantum Technologies Collaboration board member Simon Gerber. The findings have been recently published in Science.

Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

For the first time, researchers have produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Paul Scherrer Institute, in collaboration with their research partners, published the findings in the journal Nature Communications.

3-D X-ray imaging makes the finest details of a computer chip visible

Media Releases Materials Research Micro- and Nanotechnology Matter and Material Research Using Synchrotron Light

Researchers at the PSI have made detailed 3-D X-ray images of a commercially available computer chip. In their experiment, they examined a small piece that they had cut out of the chip beforehand. This sample remained undamaged throughout the measurement. It is a major challenge for manufacturers to determine if, in the end, the structure of their chips conforms to the specifications. Thus these results represent one important application of an X-ray tomography method that the PSI researchers have been developing for several years.

Matter and Material Research Using Synchrotron Light

In a series of experiments at the Swiss Light Source SLS, physicists from the Paul Scherrer Institute PSI have discovered a particle, the existence of which was predicted eighty-six years ago. It is a member of the particle family that also includes the electron, the carrier of electrical currents. The particle now discovered is massless and can exist only within a special class of materials known as Weyl semi-metals.

Insulator makes electrons move in an ordered way

Media Releases Research Using Synchrotron Light Materials Research Matter and Material

Researchers at the PSI, the EPFL and the Chinese Academy of Science, have proven that the material SmB6 shows all the properties of a so called topological insulator – a material with electric currents flowing along its surface with all of them being polarized. Here, the property is very robust, i.e. the only current that can flow is spin polarized and is not easily destroyed by small irregularities in the structure or composition of the material. Spin polarized currents are necessary for spintronics, electronics using the electrons’ spin.

Slowed down current could point the way to energy-saving computers

Media Releases Matter and Material Research Using Synchrotron Light

Computers and other electronic devices account for a substantial portion of worldwide energy use. With today’s technologies, it is not possible to reduce this energy consumption significantly any further; chips in the energy-saving electronics of the future will hence have to be made from novel materials. Researchers at the Paul Scherrer Institute PSI have now found important clues in the search for such materials.
