  • Quasiparticle poisoning challenges the operation of superconducting qubits, but errors can be suppressed by engineering gap asymmetry between the electrodes of the qubit’s Josephson junction. The authors present a model of the qubit-quasiparticle system valid beyond the low-temperature limit and identify different nonequilibrium regimes, which can affect the interpretation of experimental data.

  • While commonly the intrinsic particle–hole symmetry of superconductors prevents their exploitation for thermoelectricity, now a thermoelectric Josephson engine made from superconducting tunnel junctions gives rise to bipolar thermoelectricity and may find wide application in quantum technology.
