  • The conducting surface states of 3D topological insulators are two-dimensional. In an analogous way, the edge states of 2D topological insulators are one-dimensional. Direct evidence of this one-dimensionality is now presented, by means of scanning tunnelling spectroscopy, for bismuth bilayers—one of the first theoretically predicted 2D topological insulators.

  • Typical quantum error correcting codes assign fixed roles to the underlying physical qubits. Now the performance benefits of alternative, dynamic error correction schemes have been demonstrated on a superconducting quantum processor.

  • 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.

  • Helical Dirac fermion states in topological insulators could enable dissipation-free spintronics and robust quantum information processors. A study of the influence of disorder on these states shows that although they are resilient against backscattering by magnetic impurities, fluctuations caused by charge impurities could cause problems for such applications.

  • Borophene, a two-dimensional boron sheet, can adopt a variety of polymorphic structures that are predicted to possess interesting and potentially useful electronic properties. Micrometre-scale single-crystal borophene domains have now been grown on a square-lattice Cu(100) surface. The resulting boron sheets feature a rectangular unit cell, intrinsic stripe modulations and an unusual electron band structure.

  • The study of the band structure and crystal symmetry of the semimetal bismuth indicates that this material is a higher-order topological insulator hosting robust one-dimensional metallic states on the hinges of the crystal.

  • Superconducting single-photon detectors are critical for quantum communication, fluorescence lifetime imaging and remote sensing, but commonly operate at very low temperatures. Now, high-temperature cuprate superconducting nanowires enable single-photon detection up to 25 K.
