Air bridges rise above the plane of a circuit and are essential elements for dense, low-crosstalk signal routing in superconducting quantum circuits, but the microwave loss that they typically introduce has limited their scalability and functionality. This work presents a subtractive hard-mask fabrication process for niobium air bridges with no measurable extra loss. Beyond routing, the authors use these structures to form low-loss vacuum-gap capacitors, and incorporate those into transmon qubits with lifetimes above 50 µs. These results establish niobium air bridges as scalable, low-loss building blocks for superconducting quantum hardware.

Laser spectroscopy of the Th-229 nuclear isomer promises a fresh class of optical clocks, and precision tests of fundamental physics, but progress has been limited by the lack of an intense, narrow-linewidth continuous-wave laser near 148 nm. This work proposes a resonance-enhanced four-wave-mixing scheme to generate coherent continuous-wave light at 148 nm in cadmium vapor, using readily available pump lasers. The approach predicts tens of microwatts of output power with high coherence, potentially enabling coherent driving of the extremely weak nuclear transition, and thus overcoming a key technical bottleneck for nuclear-clock development and vacuum-ultraviolet precision spectroscopy.

The scalability of high-fidelity superconducting two-qubit gates is being held back by the struggle to balance high gate speed with low crosstalk and minimal calibration complexity. This study uses a transmon coupler, driven by analytically derived microwave pulses, between two fluxonium qubits to implement a fast conditional phase gate. Careful pulse shaping can suppress unwanted excitations sufficiently to allow gate times below 60 ns. This insight into optimized control pulses for frequency-selective two-qubit gates offers a robust pathway to tomorrow’s lower-error, easier-to-calibrate superconducting quantum processors.

Global quantum networking will be needed for quantum secured communication, and for linking distant quantum computers. Its terrestrial realization is held back by exponential photon loss in optical fibers, though, so we turn to space. The authors propose a quantum repeater architecture based on low-earth-orbit satellites that transmit entangled photons to single-atom quantum memories. They quantify the system’s expected performance, in terms of entanglement distribution rates and fidelities, and suggest a multiplexing approach to enable entanglement creation across distances of 10,000–20,000 km, bringing a global quantum Internet within reach.

Probing the interface of topological insulators and ferromagnets has proven persistently challenging, despite its relevance for spintronic applications such as spin-charge interconversion. This work provides a powerful methodology to separate bulk and interfacial spin processes based on their different dynamics. The authors optically inject femtosecond spin currents from a ferromagnetic metal into an adjacent thin film of the topological insulator BiTe. The twofold dynamics of the resulting femtosecond charge current contain signatures of spin-charge interconversion by the bulk inverse spin Hall effect and the interfacial inverse Edelstein effect.

Fast transport of Na limits the rate capability of next-generation sodium-ion batteries, and remains a longstanding challenge for high-energy cathode materials. Using an ab initio evolutionary search combined with first-principles calculations, this study identifies two metastable NaMnO polymorphs that host unusually open Na coordination environments, stabilized by high-pressure synthesis. These phases exhibit extremely low Na migration barriers, while maintaining competitive operating voltages and robust structures during (de)sodiation. The results highlight metastability as a powerful design principle for fast-ion-conducting cathodes beyond conventional layered frameworks.

The stellarator concept for future fusion reactors has a key advantage over the tokamak, being practically immune to large-scale disruptions. The authors show, however, that a rapid shutdown of stellarator coil currents (with fast dissipation of poloidal magnetic flux) can nonetheless drive an avalanche of runaway electrons, even without any interruption of the net toroidal plasma current. The problem is far less serious than in a tokamak, but some runaways are inevitably present in an activated fusion device, so an accidental rapid coil ramp-down could produce a dangerous runaway current. Some form of dedicated intervention is likely necessary.

While spin-correlated radical pairs have shown promise for molecular-scale quantum technologies, core questions remain about how they function as a chemical compass for magnetosensing. Conventional thinking suggests that unavoidable interradical interactions and uncontrolled dissipation should degrade magnetic field sensitivity. However, this theory work shows that interradical motion in biophysical settings can push magnetometry close to the Cramér-Rao bound and increase precision to subdegree levels. Even more remarkably, environmental complexity and spin-spin interactions can increase the fraction of usable information encoded in the spin dynamics, rather than degrading coherence.

Discrete-time‑crystalline (DTC) order is attractive for quantum information, sensing, and precision metrology because its subharmonic rigidity offers a route to noise‑resilient operation. Its broader utility has been limited, though, by incomplete understanding of the mechanisms that stabilize DTC phases in realistic many‑body systems, and by the difficulty of engineering platforms where such phases are tunable and robust. This work uses a periodically driven nanoelectromechanical system to realize and control multiple, distinct DTC regimes, revealing a richer dynamical landscape than was previously recognized.

In quantum information processing, spin-orbit interactions enable all-electric spin control but are often seen as incompatible with scalable exchange-only qubits designed to reduce crosstalk, heating, and control overhead. The authors show that this conflict is not fundamental: An exchange-only spin-orbit qubit can exploit spin-orbit interactions while preserving exchange-only scalability. A degenerate two-state encoding removes the need for fast clocks, and even enables more efficient simple, low-leakage two-qubit gates in a single step. More broadly, this work positions spin-orbit interactions as a resource, not a barrier, in scalable solid-state quantum architectures.

Coherence between spatially distant quantum systems is a prerequisite for many quantum technologies. Collective emission effects of multiple indistinguishable quantum emitters provide a demonstration of spatial coherence. The authors present a scalable waveguide device that enables the control of superradiance from spatially separated InAs quantum dots via independent electric tuning. Superradiance is confirmed by measuring both the quantum dot decay dynamics and the photon statistics of the emitted light, and coherence is present even at large energetic detuning of the dots.

Nanomechanical waveguides are desirable components in quantum acoustics, but their applications are limited by the ability to prevent phonon loss and decoherence while coupling to electromagnetic circuits. This study solves both problems by introducing a nanomechanical waveguide that combines piezoelectric coupling to circuits with confined phonons in a silicon waveguide metamaterial. The authors discover correlated dephasing, which is relevant to quantum device applications and suggests a common source of frequency noise. These results introduce a device to the toolbox of phononic circuit elements for quantum acoustodynamics, with potential uses in information processing and sensing.

Underwater noise significantly impacts marine ecosystems, so its control becomes increasingly important. Existing solutions are often limited by insufficient low-frequency bandwidth, bulky structures, and deployment inconvenience. This work presents a foldable acoustic metamaterial that employs air-entrained panels to realize soft-boundary waveguides, suppressing wave propagation below a designed cutoff frequency. This lightweight, deep-subwavelength structure enables low-frequency noise attenuation over more than three octaves, demonstrating strong potential for large-scale offshore engineering applications, such as bridge pilings and wind farms.

The problem is far less serious than in a tokamak, but some runaways are inevitably present in an activated fusion device, so an accidental rapid coil ramp-down could produce a dangerous runaway current. Some form of dedicated intervention is likely necessary.

While spin-correlated radical pairs have shown promise for molecular-scale quantum technologies, core questions remain about how they function as a chemical compass for magnetosensing. Conventional thinking suggests that unavoidable interradical interactions and uncontrolled dissipation should degrade magnetic field sensitivity. However, this theory work shows that interradical motion in biophysical settings can push magnetometry close to the Cramér-Rao bound and increase precision to subdegree levels. Even more remarkably, environmental complexity and spin-spin interactions can increase the fraction of usable information encoded in the spin dynamics, rather than degrading coherence.

Stochastic Ising machines (sIMs) are promising accelerators for optimization and sampling in computational problems that can be formulated as an Ising model. The authors investigate the computational advantage of sIMs for simulating quantum magnets with neural-network quantum states, a very powerful method for probabilistic quantum simulation. Based on the autocorrelation time, the team predicts sampling advantage without requiring deployment on hardware. For massively parallel hardware sIMs a speed-up factor of 100 to 10000 is projected, suggesting that sIMs may drastically increase the scale at which probabilistic quantum simulation is possible.
