Deterministic emission of shaped microwave photons is important for high-efficiency transmission of quantum information, and thus is crucial for building long-range quantum networks. Current approaches are hindered by the need for complex flux-tunable elements, as well as a small linear range of tunable coupling. This study demonstrates a simple and scalable photon generator that modulates qubit-resonator coupling without extra elements, achieving high-fidelity photon emission with minimal spurious frequency shifts, making it a promising solution for future quantum networks using both single-rail and time-bin encoding.

How to integrate a miniature optical cavity in a linear ion trap: Shielding dielectrics and trap symmetry

Ezra Kassa, Shaobo Gao, Soon Teh, Dyon van Dinter, and Hiroki Takahashi

Phys. Rev. Applied 23, 024038 (2025) - Published 18 February, 2025

Scaling up qubit numbers remains a major challenge across all quantum computing platforms, including trapped-ion systems. A modular approach seems promising, but hinges on efficient interfaces like miniature optical cavities. Despite decades of effort, a lack of understanding of the relevant challenges has precluded integration. This study identifies key obstacles posed by dielectric optical cavities, and uncovers a critical component that alleviates their negative effects. The findings provide a clear roadmap for improving ion-trap interfacing and suggest that three-dimensional traps are more suitable than planar ones.

Interface states in two-dimensional quasicrystals with broken inversion symmetry

Danilo Beli, Matheus I.N. Rosa, Luca Lomazzi, Carlos De Marqui, Jr., and Massimo Ruzzene

Phys. Rev. Applied 23, 024039 (2025) - Published 18 February, 2025

Topological metamaterials exhibit remarkable functionality in robust energy localization and waveguiding. Passive systems mostly use periodic structures with nontrivial topological features in their band structures. While quasicrystals could significantly expand this design space by introducing other symmetry orders, their lack of periodicity adds challenges. This work demonstrates the existence of interface states induced by broken inversion symmetries in two-dimensional quasicrystals: Mass dimerization breaks inversion symmetry in a tenfold-symmetric quasicrystal lattice, producing two fivefold sublattices to create domain-wall interfaces for diffractionless waveguiding.

On-demand magnon resonance isolation in cavity magnonics

Amin Pishehvar, Zhaoyou Wang, Yujie Zhu, Yu Jiang, Zixin Yan, Fangxin Li, Josep M. Jornet, Jia-Mian Hu, Liang Jiang, and Xufeng Zhang

Phys. Rev. Applied 23, 024053 (2025) - Published 20 February, 2025

Cavity magnonics is crucial for advancing next-generation signal processing (both classical and quantum), but its uptake has been limited by the challenge of achieving on-demand isolation and control of magnons, due to quasistatic magnon-photon interactions. This study employs Floquet engineering, using time-periodic drives in a multimode hybrid magnonic system to dynamically darken magnon modes, effectively decoupling them from the electromagnetic environment. By tuning the relative phase and amplitudes of the drives, precise control over magnon dynamics is achieved. This approach is also scalable, opening the door to large-scale, programmable hybrid magnonic circuits.

Flux-pump-induced degradation of $T_{1}$ for dissipative cat qubits

Léon Carde, Pierre Rouchon, Joachim Cohen, and Alexandru Petrescu

Phys. Rev. Applied 23, 024073 (2025) - Published 28 February, 2025

Engineering nonlinear dissipation through parametric interactions is a key ingredient in autonomous quantum error correction. In “cat” qubits bit-flip errors may be exponentially suppressed using two-photon driven dissipation, but spurious dissipative channels appear, in a process that is poorly understood. The authors turn to high-order perturbation theory and exact numerical diagonalization to classify the possible decay mechanisms that reduce the coherence of such a qubit, bridging the gap between the microscopic parameters of the circuit and the lifetimes of the modes. Furthermore, engineering constraints on the surrounding apparatus are identified, to reduce decoherence.

Sensing an alternating-current signal beyond the cutoff frequency using a single-electron dynamic random-access memory

Phys. Rev. Applied 23, L021001 (2025) - Published 5 February, 2025

Single-electron devices are critical for quantum computing and precision sensing, but are limited by high resistance and slow operation. This study applies a nonequilibrium-thermodynamics approach to a nanoscale dynamic random-access memory (DRAM) device monitoring a small number of electrons, enabling it to detect high-frequency signals up to six orders of magnitude higher than the DRAM’s cutoff frequency. These insights could advance high-sensitivity sensors and electronic systems, as well as offer avenues for designing low-consumption, high-frequency sensors.

Nanoscale chirality enhancement using topology-designed three-dimensional dielectric nanogap antennas

Atsushi Taguchi, Yamato Fukui, and Keiji Sasaki

Phys. Rev. Applied 23, L021002 (2025) - Published 11 February, 2025

Optical chirality enhancement and confinement at the nanoscale are crucial for amplifying chiral light-matter interactions with nanostructures, but challenges remain in designing efficient chiral nanophotonic structures, and in understanding their complex near-field behavior. This work leverages topology optimization, a high-degree-of-freedom design technique, to create a dielectric chiral gap antenna with an enhanced chiroptical effect. Here the chirality flux injected by circularly polarized light is squeezed and confined within a subwavelength mode volume through the designed nanogap structure. This approach could promote nanoscale chiral molecular sensing and spectroscopy.

Phys. Rev. Applied 23, L021003 (2025) - Published 18 February, 2025

The comparison of optical clocks from ground to space will provide unprecedented tests of fundamental physics. Such comparison is limited, though, by the relative motion between the clocks. The experiment in this Letter demonstrates a method to compensate for Doppler shifts over a rapidly moving free-space optical drone link, using an electro-optic modulator. The authors demonstrate Doppler-shift compensation up to 18 MHz, providing a path toward ground-to-space optical comparison.

Engineering nonlinear dissipation through parametric interactions is a key ingredient in autonomous quantum error correction. In “cat” qubits bit-flip errors may be exponentially suppressed using two-photon driven dissipation, but spurious dissipative channels appear, in a process that is poorly understood. The authors turn to high-order perturbation theory and exact numerical diagonalization to classify the possible decay mechanisms that reduce the coherence of such a qubit, bridging the gap between the microscopic parameters of the circuit and the lifetimes of the modes. Furthermore, engineering constraints on the surrounding apparatus are identified, to reduce decoherence.
