  • Recently, nonlinear effects have been studied in systems with a nonlinear transmon qubit coupled to a linear low-impedance resonator. Here the authors realize a high-impedance resonator using a single Josephson junction, where strong nonlinear effects emerge already when the second photon enters the resonator.

  • By coupling a spin-qubit to a superconducting resonator, remote spin-entanglement becomes feasible. Here, Ungerer et al achieve strong coupling between a superconducting resonator and a singlet-triplet spin qubit, in an InAs nanowire.

  • The performance of superconducting devices can be degraded by quasiparticle generation mechanisms that are difficult to identify and eliminate. Now, a small superconducting island can be kept quasiparticle free for seconds at a time.

  • The fluctuation relations are a central concept in thermodynamics at the microscopic scale. These relations are experimentally verified by measuring the entropy production in a single-electron box coupled to two heat baths.
