  • An array of superconducting nanocircuits has been designed that provides built-in protection from environmental noises. Such ‘topologically protected’ qubits could lead the way to a scalable architecture for practical quantum computation.

  • Disorder leads to localization of electrons at low temperatures, changing metals to insulators. In a superconductor the electrons are paired up, and scanning tunnelling microscopy shows that the pairs localize together rather than breaking up and forming localized single electrons in the insulating state.

  • Experimental measurements of high-order out-of-time-order correlators on a superconducting quantum processor show that these correlators remain highly sensitive to the quantum many-body dynamics in quantum computers at long timescales.

  • A first-order, disorder-driven, superconductor–insulator phase transition is demonstrated. This is in contrast with the usually observed second-order transition and highlights the role of Coulomb interactions between preformed Cooper pairs.

  • Experiments with superconductor–graphene hybrids, a novel platform to study quantum phase transitions, suggest that in the proximity of the critical point between superconducting and insulating phases, inhomogeneity emerges at large scales even in apparently uniform disordered systems.

  • Two below-threshold surface code memories on superconducting processors markedly reduce logical error rates, achieving high efficiency and real-time decoding, indicating potential for practical large-scale fault-tolerant quantum algorithms.
