Study links surface roughness to performance in superconducting radiofrequency cavities

by

With every new particle accelerator built for research, scientists have an opportunity to push the limits of discovery. But this is only true if new particle accelerators deliver the desired performance—no small feat in a world where each new machine is a first of its particular kind. At each project opportunity, researchers try to refine … Read more

Niobium qubits rise from the ashes with new design and fabrication

by

For years, niobium was considered an underperformer when it came to superconducting qubits. Now, scientists supported by Q-NEXT have found a way to engineer a high-performing niobium-based qubit and take advantage of niobium’s superior qualities. When it comes to quantum technology, niobium is making a comeback. For the past 15 years, niobium has been sitting … Read more
