Because of their large bandwidth and excellent noise performance, superconducting traveling-wave parametric amplifiers are key components for multiplexed readout of superconducting qubits. Their 1-dB compression power is too low, however, and hinders practical use. The authors show experimentally that there are two causes of gain compression in these amplifiers: the expected pump depletion, which decreases the energy available for amplification, and an unexpected power-induced phase-mismatch effect, which makes the amplification interaction less effective. These results will help in designing better superconducting amplifiers for applications with high power demands.

Cavity optomechanics is a powerful tool for mechanical sensing, but the most sensitive interferometers are inherently destabilized by thermal vibrations. Radiation forces can partially mitigate this with cooling or stiffening, yet inevitably introduce their own destabilizing effects at high power, creating a frustrating competition between stability and sensitivity. This study reveals that photothermal effects in mirror coatings can simultaneously stiffen and cool about 100 mechanical modes, without those instabilities. The authors also share intuition for enhancing these effects with modified coatings, opening a pathway to stable operation at higher power with improved precision.

Addressing individual quantum emitters coupled to a waveguide is challenging, as local control is hard to engineer and subwavelength focusing cannot be trivially achieved. This study shows that the nonlinear dispersion of a waveguide combined with a wide-band chirped pulse can be used to achieve subwavelength addressing of superconducting qubits embedded in a microwave waveguide. This technique can be applied in a wide range of quantum optics experiments, such as those on atoms coupled to optical fibers, or on solid-state spin qubits (e.g. the nitrogen-vacancy center in diamond) coupled to optical waveguides.

Magnetic force microscopy has many important applications in industry and academic research. One of the main challenges in such applications is to distinguish magnetic information from electrostatic and topographical signals. In this work, the authors experimentally demonstrate a method for in situ differential imaging using a switchable magnetic tip. The technique allows one to perform pixel-by-pixel differential magnetic force microscopy, and is ideally suited for sensing with ultracoherent silicon nitride membranes.

Time-varying photonic media present fresh opportunities for light control, with most studies focusing on periodic modulations. This work investigates photonic time quasicrystals, characterized by aperiodic yet deterministic temporal patterns, through the use of trace and antitrace map formalisms. Analysis of Thue-Morse and Fibonacci sequences reveals complex spectral features, including fractal band gaps and quasilocalized wave states. The findings indicate that aperiodic temporal order may offer further possibilities for the design of photonic systems with enhanced spectral-shaping and localization capabilities.

The authors demonstrate that perpendicularly magnetized magnetic tunnel junctions 50 nm in diameter (fully compatible with conventional electronics) can switch magnetization with very low power in nanoseconds or less, which is faster than previously believed. These measurements align with a theoretical model that highlights the surprising role of entropy, revealing femtosecond-scale Arrhenius prefactors. This finding overturns an assumed speed limit in the field and opens the door to scalable, ultrafast, low-power computing technologies that harness thermal noise as a functional resource at the nanoscale.

Magnetic topological insulators (TIs) hold promise for advanced spintronic and sensing technologies, yet their potential is hindered by electronic backscattering from magnetic impurities, and the consequent resistance and dissipation in a device. The authors reveal that high-frequency linearly polarized light, after coupling to hexagonally warped surface states of the TI, can entirely eliminate this backscattering and enable dissipationless transport in magnetic TIs. Besides the energy savings, this dependence of conductance on the polarization angle and intensity of light points to unanticipated optical-sensing abilities in these materials.

Although antiferromagnetic magnons can propagate over long distances, this work shows that such long-range transport can be significantly suppressed. By fabricating a homoepitaxial film upon its bulk crystal, the authors find that magnons from the bulk are scattered by point defects in the film, hindering their flow. The team precisely monitors this phenomenon using the spin Seebeck effect. The results highlight the critical role of spin disorder in controlling magnon propagation, which is of interest to the spintronics community.

Conventional digital systems struggle with the complexity of NP-complete problems due to sequential processing and energy inefficiency, and this motivates alternative computing paradigms inspired by physical dynamics. This study presents a CMOS network of injection-locked ring oscillators that solve Boolean satisfiability problems by mapping them onto Ising models, to realize a fully invertible one-bit full adder in hardware. The approach leverages the analogy between Ising spin interactions and the synchronization of oscillator phases to binary states via injection locking.

Ising machines offer hardware acceleration for combinatorial optimization, artificial intelligence, and quantum simulation, but their reliance on dense graphs restricts large-scale deployment. To address this limitation, the authors introduce a sparsification algorithm that distributes each node’s connections across multiple copies, enabling constant-frequency operation in ASIC designs and FPGA prototypes. Evaluation of runtime overhead during optimization tasks reveals a trade-off between hardware feasibility and execution time; notably, this overhead vanishes for inherently sparse problems such as integer factorization.
