Electrically switchable qubit can tune between storage and fast calculation modes

To perform calculations, quantum computers need qubits to act as elementary building blocks that process and store information. Now, physicists have produced a new type of qubit that can be switched from a stable idle mode to a fast calculation mode. The concept would also allow a large number of qubits to be combined into […]

Quick and sensitive identification of multidrug-resistant germs

Researchers from the University of Basel have developed a sensitive testing system that allows the rapid and reliable detection of resistance in bacteria. The system is based on tiny, functionalized cantilevers that bend due to binding of sample material. In the analyses, the system was able to detect resistance in a sample quantity equivalent to […]

How bacteria reinforce their protective shield

Researchers at the University of Basel have discovered a new mechanism by which bacteria ensure that their outer cell membrane remains intact and functional even under hostile conditions. This mechanism is important for the pathogen’s survival in the host. The study provides new insights underlying pathogenic virulence. When infecting a host, pathogens not only need […]

Tiny fish under a giant camera

Metal-based nanoparticles are a promising tool in medicine – as a contrast agent, transporter of active substances, or to thermally kill tumor cells. Up to now, it has been hardly possible to study their distribution inside an organism. Researchers at the University of Basel have used a three-dimensional imaging method to take high-resolution captures inside […]
