Spin correlation between paired electrons demonstrated

Physicists at the University of Basel have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a superconductor. For their study, the researchers used spin filters made of nanomagnets and quantum dots, as they report in the scientific journal Nature. The […]

Ultracold circuits

Cooling materials to extremely low temperatures is important for basic physics research as well as for technological applications. By improving a special refrigerator and a low-temperature thermometer, Basel scientists have now managed to cool an electric circuit on a chip down to 220 microkelvin – close to absolute zero. When materials are cooled down to […]

Coupling of electron-hole pairs

For the first time, physicists from the University of Basel have succeeded in coupling different types of electron-hole pairs (excitons) in the van der Waals material molybdenum disulfide. This successful coupling allows them to utilize and control the different properties of the two types of electron-hole pairs — and could pave the way for the […]

Twin photons from unequal sources

Identical light particles (photons) are important for many technologies that are based on quantum physics. A team of researchers from Basel and Bochum has now produced identical photons with different quantum dots – an important step towards applications such as tap-proof communications and the quantum internet. Many technologies that make use of quantum effects are […]

Cooling matter from a distance

Researchers from the University of Basel have succeeded in forming a control loop consisting of two quantum systems separated by a distance of one meter. Within this loop, one quantum system — a vibrating membrane — is cooled by the other — a cloud of atoms, and the two systems are coupled to one another […]

New rapid test could detect coronavirus and flu simultaneously

Researchers from the University of Basel and the Paul Scherrer Institute PSI have developed a rapid test for Covid-19 with a novel functional principle. Although it requires further testing and improvements, the initial results are promising: As well as determining whether a Covid-19 infection is present, the test also promises to provide information on the […]
