Phys. Rev. Applied 26, 024025 (2026) - Published 11 August, 2026

Superconducting qubits are promising for quantum computing, but their performance is hindered by correlated errors from environmental factors like ionizing radiation and cryocooler vibrations. The authors distinguish these error types in the same device by their distinct features, and use accelerometers to directly link specific errors to pulse tube vibrations. This study also reveals that qubits engineered to resist radiation are protected against these vibration-induced errors as well. Identifying the sources of correlated errors will inform future mitigation strategies for building more robust quantum computers.

Establishing the magnetoelastic origin of spin-wave routing through focused-ion-beam patterning

Felix Naunheimer, Johannes Greil, Valentin Ahrens, Levente Maucha, Ádám Papp, György Csaba, and Markus Becherer

Phys. Rev. Applied 26, 024028 (2026) - Published 12 August, 2026

Spin waves hold promise for compact analog computing, but routing them via focused-ion-beam irradiation in yttrium iron garnet is hindered by a nonmonotonic wavelength response to ion dose. By combining atomic force microscopy and time-resolved magneto-optical Kerr effect microscopy with analytical, ion-damage, and micromagnetic modeling, this study links this response to the progression from elastic and plastic deformation to partial amorphization and the resulting magnetoelastic fields. This physical understanding will enable predictably engineered irradiation-defined spin-wave landscapes and future graded-index magnetoelastic magnonic devices.

Semiconductor-quality pyrite ${FeS}_{2}$ from iron ore

Yeon Lee, Jennifer T. Mitchell, Caitlyn Komar, Matt Mlinar, Jestos Taguta, George Hudak, and Chris Leighton

Phys. Rev. Applied 26, 024033 (2026) - Published 13 August, 2026

Pyrite FeS $_{2}$ is an earth-abundant, low-cost semiconductor with application potential, particularly if it can be synthesized at high quality from natural resources. This study demonstrates that common iron ores can be converted directly to semiconductor-quality FeS $_{2}$ without additional purification, because unexpected purification occurs during processing and few elements effectively dope the material. The resulting single crystals boast carrier densities down to 10 $^{16}$ cm $^{- 3}$ and mobilities up to 100 cm $^{2}$ V $^{- 1}$ s $^{- 1}$ , similar to those grown from high-purity precursors. This could unlock an attractive new revenue stream for an abundant natural resource.

Fast and sensitive readout of a semiconductor quantum dot using an in situ microwave resonator with enhanced gate lever arm

Tim J. Wilson and Hong-Wen Jiang

Phys. Rev. Applied 26, 024040 (2026) - Published 14 August, 2026

Quantum dot–based spin qubits require ultrafast, high-fidelity charge readout for quantum error correction and real-time feedback. Improving readout sensitivity has often required complex high-impedance resonators or specialized circuits. This work shows that optimizing a gate lever arm directly coupled to an in situ superconducting microwave resonator dramatically enhances readout sensitivity, achieving integration times at the tens of nanoseconds scale without the use of high-impedance devices, and revealing how readout noise evolves across distinct physical regimes. These results show a practical route toward faster, more scalable architectures for fault-tolerant quantum computing.

Volatile resistive-switched state in a bulk organic conductor with a sharp metal-insulator transition

Riku Ishii, Ryo Motohashi, Keitaro Tada, Yusuke Suzuki, Takayoshi Kouchi, Hiroshi Oike, Fumitaka Kagawa, Reizo Kato, and Tetsuaki Itou

Phys. Rev. Applied 26, 024041 (2026) - Published 17 August, 2026

Volatile resistive switching in correlated-electron systems is promising for electronics applications, but the underlying physics remains obscured. Most studies have focused on inorganic thin films on substrates with strong thermal coupling to their surroundings, but here the authors investigate in a bulk organic single crystal with an exceptionally sharp metal-insulator transition. Bulk-sensitive microscopic NMR reveals the coexistence of metallic and insulating regions in the resistive-switched state, while weak thermal coupling to the surroundings allows temperature locking near the transition temperature and an “inverse Ohm’s law”, with voltage inversely proportional to current.

Scalable simulation of quantum many-body dynamics with or-represented quantum algebra

Lukas Broers, Rong-Yang Sun, and Seiji Yunoki

Phys. Rev. Applied 26, 024046 (2026) - Published 18 August, 2026

Powerful and efficient numerical techniques have been central to theoretical research on quantum mechanical systems for decades. In the era of quantum advantage demonstrations, it is paramount to develop strong benchmarks that truly represent the classical frontier. This study presents a high-performance parallel implementation and large-scale demonstration of quantum dynamics simulated with OR-represented quantum algebra at a huge scale, retaining over a trillion Pauli strings while maintaining strong scaling behavior, using the supercomputer Fugaku. This algorithm enriches the body of classical high-performance methods and challenges current quantum advantage efforts.

Timing jitter induced by stochastic baseline fluctuations in high-count-rate superconducting nanowire single-photon detectors

Dianpeng Wang, You Xiao, Jiamin Xiong, Chenrui Wang, Zhen Wan, Hongxin Xu, Chaomeng Ding, Jia Huang, Lixing You, and Hao Li

Phys. Rev. Applied 26, 024049 (2026) - Published 18 August, 2026

Superconducting nanowire single-photon detectors with high count rates are important for quantum information processing, optical communication, and photon-starved imaging. Their timing performance is limited by excess jitter, though, and the underlying physics is not fully understood. This study identifies stochastic baseline fluctuations caused by the finite memory of ac-coupled readout circuits as an important source of timing jitter at high count rates, and establishes a quantitative framework to predict their impact. Also, under pulsed illumination the timing jitter is found to reach a maximum at about half of the laser’s repetition rate.

Electromechanical coupling at tunable band extrema in flexoelectric metamaterials

Kshiteej J. Deshmukh, Ihina Mahajan, Alper Erturk, and Pradeep Sharma

Phys. Rev. Applied 26, 024063 (2026) - Published 24 August, 2026

Stopping and localizing elastic waves can concentrate energy for high-sensitivity sensing and harvesting, but this often requires intricately tuned lattices or symmetry-restricted piezoelectric transducers. This study finds that flexoelectricity—the universal coupling between strain gradients and electric polarization—could be combined with higher-order elasticity to create stable, tunable zero-group-velocity extrema and stationary-inflection modes. Introducing a defect cavity for tighter localization increases both open-circuit voltage and mass responsivity. The resulting self-sensing, electrically reconfigurable resonators could enable compact devices for diverse applications.

Battery-free wireless quartz-crystal-microbalance sensor operating at a range of 50 m

Motoyuki Hamana, Ambuj Kumar Gautam, Motoharu Haga, Riki Nishihara, Wenlou Yuan, Fumihito Kato, Nobutomo Nakamura, Hiroki Okita, and Hirotsugu Ogi

Phys. Rev. Applied 26, 024067 (2026) - Published 24 August, 2026

Starting from a quartz-crystal microbalance, the authors develop a battery-free wireless sensing technology that enables remote measurements of structural strain and gas concentration over distances exceeding 50 m. The system enhances the electromechanical coupling between an AT-cut quartz resonator (packaged in a slightly pre-bent state) and electromagnetic waves, enabling long-range sensing without onboard power sources or electrical connections. The ability to perform battery-free long-range sensing is promising for smart infrastructure monitoring, with applications in bridges, pipelines, nuclear facilities, and industrial plants.

Interlayer chiral coupling between an insulating ferrimagnet and a conducting ferromagnet with orthogonal magnetizations

Weronika Janus, Takayuki Shiino, and Can Onur Avci

Phys. Rev. Applied 26, L021001 (2026) - Published 5 August, 2026

Chiral interlayer coupling is promising for field-free spintronic memory and logic, but has remained largely unexplored in simple bilayers combining a ferrimagnetic insulator and a conducting ferromagnet. The authors study the Tb $_{3}$ Fe $_{5}$ O $_{12}$ /Co $_{40}$ Fe $_{40}$ B $_{20}$ system and reveal a tunable chiral exchange bias acting on both magnetic layers. Temperature-controlled and current-induced Joule heating drive the system from a disfavored to a favored chiral configuration, enabling deterministic perpendicular magnetization reversal of Tb $_{3}$ Fe $_{5}$ O $_{12}$ . These results establish insulating-ferrimagnetic-garnet/ferromagnet bilayers as a promising platform for chiral spintronic devices.

Reflection and refraction properties of a laser-driven two-dimensional quantum well: Analogy to a photonic time crystal

Igor V. Smetanin and Alexander V. Uskov

Phys. Rev. Applied 26, L021002 (2026) - Published 6 August, 2026

This Letter presents an innovative type of metamaterial that exhibits photonic-crystal-like Floquet scattering when exposed to an obliquely incident, weak electromagnetic probe wave. A laser-driven two-dimensional quantum well modulates the photoexcited electron density at the beat frequency of the laser radiation, behaving as a polychromatic source of radiation. Backward-propagating and surface-bound down-shifted satellites, including TE surface modes, are predicted. The proposed scheme provides a roadmap for extending photonic time crystals to the terahertz and near-infrared frequency domains.

Robust Bayesian spin-squeezing-enhanced quantum sensing under noise

Jinye Wei, Jungeng Zhou, Yi Shen, Jiahao Huang, and Chaohong Lee

Phys. Rev. Applied 26, L021003 (2026) - Published 6 August, 2026

Spin-squeezed states can surpass the standard quantum limit, yet their advantage is confined to a narrow phase range, complicating their use in noisy sensors. The authors present an adaptive Bayesian quantum estimation protocol that locks interferometry to its optimal operating point and incorporates phase noise into a reshaped likelihood function. Applied to quantum gravimeters and atomic clocks, this approach substantially enhances precision and outperforms conventional fringe-fitting protocols under noise. This framework establishes a noise-resilient pathway for entanglement-enhanced sensing, advancing high-precision measurements in geophysics, navigation, and timekeeping.

Micromagnetic modeling of surface acoustic wave—driven dynamics: Interplay of strain, magnetorotation, and magnetic anisotropy

Florian Millo, Pauline Rovillain, Massimiliano Marangolo, and Daniel Stoeffler

Phys. Rev. Applied 26, L021004 (2026) - Published 14 August, 2026

This Letter investigates the coupling mechanism of surface acoustic waves (SAWs) with spin waves (SWs) via micromagnetic analysis. The SAW magnetoacoustic excitation field is fully implemented (all strain and lattice-rotation terms included) in a realistic Co-Fe-B film with weak in-plane uniaxial anisotropy. Resonance alone does not guarantee efficient coupling; weak in-plane anisotropy can reshape the SAW-SW coupling, while lattice rotation can enhance and restructure the absorption features. Particular emphasis is put on the case where a SAW propagates parallel to the external magnetic field, a configuration of special interest for magnonics.

Fast, high-fidelity baseband reset of a latched state for readout of a quantum dot qubit

Piotr Marciniec, M. A. Wolfe, Tyler Kovach, J. Reily, Sanghyeok Park, Jared Benson, Mark Friesen, Benjamin D. Woods, Matthew J. Curry, Nathaniel C. Bishop, J. Corrigan, and M. A. Eriksson

Phys. Rev. Applied 26, L021005 (2026) - Published 21 August, 2026

Fast, high-fidelity qubit measurement and initialization are important for minimizing errors in quantum algorithms. Latched readout is a powerful technique for high-fidelity measurement of a spin qubit, but with it come inherently long initialization times. This Letter presents a fresh initialization technique that takes advantage of a fast, two-step decay process to achieve better than 50-fold speedup over passive initialization of latched readout states. This multistep technique uses a low-amplitude pulsing scheme to achieve fast qubit initialization, comparable to simpler single-step techniques, while relieving technical complications that can arise.

Superconducting nanowire single-photon detectors with high count rates are important for quantum information processing, optical communication, and photon-starved imaging. Their timing performance is limited by excess jitter, though, and the underlying physics is not fully understood. This study identifies stochastic baseline fluctuations caused by the finite memory of ac-coupled readout circuits as an important source of timing jitter at high count rates, and establishes a quantitative framework to predict their impact. Also, under pulsed illumination the timing jitter is found to reach a maximum at about half of the laser’s repetition rate.

Electromechanical coupling at tunable band extrema in flexoelectric metamaterials

Stopping and localizing elastic waves can concentrate energy for high-sensitivity sensing and harvesting, but this often requires intricately tuned lattices or symmetry-restricted piezoelectric transducers. This study finds that flexoelectricity—the universal coupling between strain gradients and electric polarization—could be combined with higher-order elasticity to create stable, tunable zero-group-velocity extrema and stationary-inflection modes. Introducing a defect cavity for tighter localization increases both open-circuit voltage and mass responsivity. The resulting self-sensing, electrically reconfigurable resonators could enable compact devices for diverse applications.

Starting from a quartz-crystal microbalance, the authors develop a battery-free wireless sensing technology that enables remote measurements of structural strain and gas concentration over distances exceeding 50 m. The system enhances the electromechanical coupling between an AT-cut quartz resonator (packaged in a slightly pre-bent state) and electromagnetic waves, enabling long-range sensing without onboard power sources or electrical connections. The ability to perform battery-free long-range sensing is promising for smart infrastructure monitoring, with applications in bridges, pipelines, nuclear facilities, and industrial plants.

This work introduces a unified platform supporting topological states for both electromagnetic and elastic waves, within the same artificial crystal. While topological photonic and phononic systems typically are investigated independently, the approach here enables direct comparison of their topological properties and transport behaviors in the selfsame geometry. Breaking a specific spatial symmetry in a graphenelike lattice opens valley-polarized topological band gaps in both physical domains, yielding interfacial states between topologically distinct crystals. The authors establish a general, unifying framework for topological photonics and phononics.
