Previous research found that twisted bilayer graphene is superconductive when the layers are rotated by 1.08 degrees. Electrons in parts of these materials move very slowly and should therefore not conduct electricity at all, much less display superconductivity. New research shows how the current theory of superconductivity, the Bardeen-Cooper-Schrieffer (BCS) theory, must be modified to fit the observations of twisted bilayer graphene.

But now a group at Stanford University and the University of Chicago has demonstrated a way to create niobium-based qubits that rival the state-of-the-art for their class. By restructuring and reengineering how niobium is incorporated in a component called the Josephson junction, the group developed a qubit that could maintain information for 62 millionths of a second, 150 times longer than its best-performing niobium predecessors.
