  • A phase battery is a quantum device that provides a persistent phase bias to the wave function of a quantum circuit. A hybrid superconducting and magnetic circuit containing two anomalous Josephson junctions can provide a tunable Josephson phase that persists in the absence of external stimuli.

  • 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.

  • Superconducting computing promises enhanced computational power, but scalable and fast superconducting memories are still not implemented. Here, the authors demonstrate a superconducting memory cell based on hysteretic phase-slip transition, without degradation up to ~1 K over several days.

  • The sign of switching currents in supercurrent diodes depends on their flow direction, however effective strategies to control it in single platforms with large efficiency are missing. The authors realise a supercurrent diode in superconducting weak links that is tunable both in amplitude and sign of switching current by an out of-plane magnetic field in a regime without magnetic screening.

  • Diodes are characterized by mono-directional flow of current, yet this simplicity belies their critical importance in electronics and optics. Here, Strambini et al demonstrate a superconducting quasi-particle equivalent, achieved by the use of a thin ferromagnetic insulator.

  • Physical details of a Josephson junction may drastically modify the properties of supercurrent. Here, the authors observe a colossal enhancement of the critical supercurrent in a Josephson junction subject to a perpendicular magnetic field, indicating topological phase transitions.

  • Heat transport in electronic systems is influenced by nearby superconductors due to the so-called proximity effect. Combining this with the manipulation of superconductivity using magnetic fields enables the control of nanoscale thermal transport.
