Niobium has long been considered an underperformer in superconducting qubits. Scientists have now engineered a high-quality niobium-based qubit, taking advantage of niobium's superior qualities. For ...

A niobium-based qubit can operate at higher temperatures than its aluminum counterpart, and so would require less cooling. It can also operate across an eight-times-greater frequency range and a ...

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 ...
