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 ...

Exotic superconducting states could exist in a wider range of materials than previously thought, according to a theoretical study by two RIKEN researchers published in Physical Review B.

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 ...

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 ...

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 ...

In a leap forward for quantum computing, a Microsoft team led by UC Santa Barbara physicists on Wednesday unveiled an eight-qubit topological quantum processor, the first of its kind. The chip, built ...

Today’s most powerful computers hit a wall when tackling certain problems, from designing new drugs to cracking encryption codes. Error-free quantum computers promise to overcome those challenges, but ...

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 ...

Something strange goes on inside the material platinum-bismuth-two (PtBi₂). A new study by researchers at IFW Dresden and the Cluster of Excellence ct.qmat demonstrates that while PtBi₂ may look like ...
