Decoherence is thought to be a major obstacle in using macroscopic quantum states for quantum computing applications. In his Perspective, Leggett highlights the two independent experiments by Vion et al . and Yu et al . showing that long coherence times can be achieved. The reports indicate that whatever the difficulties that may be encountered in the attempt to build a quantum computer with Josephson circuits, decoherence need not be among them.
