The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function at very low temperatures, their practical application has been severely ...

Scientists at the University of Würzburg and the German national metrology institute (PTB) have carried out an experiment that realizes a new kind of quantum standard of resistance. It's based on the ...

Here’s what you’ll learn when you read this story: Studying quantum phenomena—such as the quantum Hall effect and ‘edge state’ electrons—is incredibly difficult because they occur at such small scales ...

While conventional qubits remain as fragile as fine china, susceptible to environmental decoherence, topological qubits come naturally "armor-plated" with intrinsic fault tolerance. For decades, ...
