As part of the Quantum Science Center headquartered at ORNL, Robert Moore probes the interface between a topological insulator and a superconductor with spin- and angle-resolved photoemission ...

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly ...

Superconductors (materials that conduct electricity without resistance) have fascinated physicists for more than a century. While conventional superconductors are well understood, a new class of ...

Physicists at the University of Cologne have taken an important step forward in the pursuit of topological quantum computing by demonstrating the first-ever observation of Crossed Andreev Reflection ...

Even the fastest supercomputers struggle with certain complex tasks, such as discovering new medicines or breaking advanced encryption. Quantum ...

A cluster of recent experiments and theoretical studies has produced the strongest evidence yet that spin-triplet superconductivity can be reliably generated and controlled at material interfaces, a ...

A multi-institutional team of scientists has developed a new superconductor material that could potentially be used in quantum computing and be a candidate 'topological superconductor.' A ...

Figure 2. Spatial distribution of magnetic vortex lattice and absence of Majorana bound state in vortex core of WS2 with stripes. Figure 3. Recovered Majorana bound states in the underlying WS2 layer ...

PtBi2 looks like an ordinary grey crystal, but a new study shows its electrons move in unusual ways not seen in other materials. In 2024 (Nature, "Evidence of superconducting Fermi arcs"), the ...

Researchers at Okayama University used high-resolution synchrotron X-ray diffraction to detect tiny lattice distortions (about 100 parts per million) emerging as the topological superconductor Cu x ...
