  • Andreev bound states can form in hybrid semiconducting-superconducting devices and can mirror the experimental signatures of the much sought topologically non-trivial Majorana bound states. Here, van Driel, Wang and coauthors present a method of directly measuring the spin-polarized excitation spectrum of Andreev bound states.

  • A minimal artificial Kitaev chain can be realized by using two spin-polarized quantum dots in an InSb nanowire strongly coupled by both elastic co-tunnelling and crossed Andreev reflection.

  • A three-site Kitaev chain, constructed from three semiconducting quantum dots coupled by superconducting segments in a hybrid InSb/Al nanowire, shows enhanced robustness of edge zero-energy modes against variations in the coupling strengths or electrochemical potentials compared with a chain containing only two quantum dots.

  • A Kitaev chain formed by two quantum dots coupled via a superconductor support the so-called poor man’s Majorana bound states. Here, the authors form a minimal Kitaev chain using Yu-Shiba-Rusinov states and show that the resulting bound states are more robust than in the case of unproximitized quantum dots.

  • 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.

  • The proximity effect in semiconductor-superconductor nanowires is expected to generate an induced gap in the semiconductor. Here, the authors study the superconducting proximity effect in InSb nanowires with an Al/Pt shell, demonstrating control of the induced gap using electric and magnetic fields.

  • Here, the authors develop a spectroscopic technique whereby individual defects in an ultrathin hBN dielectric, placed in proximity to graphene, act as quantum dots. Dot-assisted tunneling is highly sensitive to the nearby graphene excitation spectrum, and allows probing of energy splitting in the excited Landau levels.

  • A quantum dot-superconductor array can form a Kitaev chain which hosts Majorana zero modes at a sweet spot. The authors examine how to enhance the excitation gap of the Majorana zero modes, which is crucial for implementing topological quantum computing with enhanced protection.
