  • Controllable non-reciprocal hopping is crucial for emerging photonic technologies. Here, the authors demonstrate a tunable microwave system exhibiting non-Hermitian, phase-non-reciprocal, and nonlinear dynamics, with potential relevance to sensing, quantum networks, and synthetic photonic materials.

  • Future quantum computers need quantum memories that store arbitrary states for long periods, without incurring significant access latencies. Using high-order dynamical decoupling sequences, this work shows a practical scheme to suppress physical errors and guarantee high-fidelity storage for long times.

  • Accurately characterizing the noise influencing quantum devices is instrumental to improve coherence properties and design more robust control protocols. Sung et al. demonstrate non-Gaussian noise spectroscopy with a superconducting qubit, enabling the detection and characterization of dephasing noise without assuming Gaussian statistics.
