Quantum researchers have dedicated significant efforts to developing superconducting qubits with a sandwich-like “SIS” junction (a), made up of two superconducting layers (Al) separated by an insulator (AlOX). But a new study from Brookhaven Lab demonstrated that qubits with constriction junctions (b) perform comparably to qubits with SIS junctions. Constriction junctions, which lay flat and consist of two superconducting layers connected by a thin superconducting wire, can be manufactured more readily at scale.
