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 a powerful quantum computer, as researchers from the University of Basel and TU Eindhoven have reported in the journal Nature Nanotechnology.
Physicists develop record-breaking source for single photons
Researchers at the University of Basel and Ruhr University Bochum have developed a source of single photons that can produce billions of these quantum particles per second. With its record-breaking efficiency, the photon source represents a new and powerful building-block for quantum technologies.
Kagome graphene promises exciting properties
For the first time, physicists from the University of Basel have produced a graphene compound consisting of carbon atoms and a small number of nitrogen atoms in a regular grid of hexagons and triangles. This honeycomb-structured “kagome lattice” behaves as a semiconductor and may also have unusual electrical properties. In the future, it could potentially be used in electronic sensors or quantum computers.
Concept for a new storage medium
Physicists from Switzerland, Germany and Ukraine have proposed an innovative new data storage medium. The technique is based on specific properties of antiferromagnetic materials that had previously resisted experimental examination.
New class of substances for redox reactions
An interdisciplinary, multinational research team presents a new class of chemical compounds that can be reversibly oxidized and reduced. The compounds known as ‘pyrazinacenes’ are simple, stable compounds that consist of a series of connected nitrogen-containing carbon rings. They are suitable for applications in electrochemistry or synthesis, as the researchers describe in the science journal Communications Chemistry.
On the way to sustainable hydrogen
Researchers in the SNI network have developed a theoretical method to analyze and optimize water splitting by exploiting optical effects. The work, published in the Journal of Physical Chemistry C, will help to advance sustainable hydrogen production without emitting CO2.
Novel antibiotic deceives bacteria through mimicry
Most antibiotics need to penetrate their target bacteria. But Darobactin, a newly discovered compound, is much too large to do so. Nonetheless, it kills many antibiotic-resistant pathogens – by exploiting a tiny weak spot on their surface. Researchers at the University of Basel’s Biozentrum have now revealed the amazing mechanism at play and thereby opened the door to developing completely new medicines.
