  • 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.

  • Topological superconductors are expected to be a key component of quantum computing systems but reliably detecting their exotic properties is a challenge. Here, the authors propose a topological Josephson heat engine which uses thermodynamic effects to probe the 4π-periodic ground state of a topological superconductor.

  • 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.
