Resurrecting Niobium for Quantum Science

The Josephson junction is the information-processing heart of the superconducting qubit. Pictured here is the niobium Josephson junction engineered by David Schuster of Stanford University and his team. Their junction design has resurrected niobium as a viable option as a core qubit material.

Expanding possibilities for superconducting qubits. 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 so take advantage of niobium’s superior qualities.

When it comes to quantum technology, niobium is making a comeback...
