  • There is a trade-off between achieving fast qubit control and preserving long qubit lifetimes. In this work, the authors demonstrate single qubit gates by driving a transmon qubit parametrically at 1/3 of its frequency, creating fast, high-fidelity gates while protecting the qubit lifetime and mitigating heating.

  • Measurements of the distribution of stochastic switching currents in homogeneous, ultra-narrow superconducting nanowires provide strong evidence that the low-temperature current-switching in such systems occurs through quantum phase slips—topological quantum fluctuations of the superconducting order parameter via which tunnelling occurs between current-carrying states.

  • Quantum dots in a nanowire are one possible approach to creating a solid-state quantum simulator. Here, the authors demonstrate the coupling of electronic states in a double quantum dot to form Andreev molecule states; a potential building block for longer chains suitable for quantum simulation.

  • The transport measurements of an interacting fermionic quantum gas in an optical lattice provide a direct experimental realization of the Hubbard model—one of the central models for interacting electrons in solids—and give insights into the transport properties of many-body phases in condensed-matter physics.

  • Exciton–polariton condensates have garnered interest as a means to access macroscopic displays of quantum phenomena such as Bose–Einstein condensation and superfluidity. In this work, a direct measure of the polariton–polariton interaction is obtained.

  • Laser performance is constrained by various factors. Here, the authors show theoretically that the linewidth can be reduced below the standard quantum limit by engineering the output coupling of a laser to reduce noise, and discuss the potential practical implementation of this approach.

  • Multiplexed hybridization probes are traditionally difficult to design with high sensitivity and specificity. Here Wu et al. present a method for fine, decoupled and on-the-fly tuning of probe behavior based on the stoichiometric formulation of a molecular competitor species.
