Metasurface-based single-pixel recognition through scattering media
Taking advantage of optoelectronic hybrid neural networks, we propose a metasurface-single-pixel hybrid neural network for object recognition. It employs only eight illumination patterns trained by th...
Enhanced size-dependent efficiency of InGaN/AlGaN near-ultraviolet micro-LEDs
This study presents an approach for enhancing the external quantum efficiency (EQE) of multiple-quantum-well InGaN/AlGaN near-ultraviolet (NUV) micro-light-emitting diodes (micro-LEDs) without changin...
Dead-zone-free single-beam atomic magnetometer based on free-induction-decay of Rb atoms
Free-induction-decay (FID) magnetometers have evolved as simple magnetic sensors for sensitive detection of unknown magnetic fields. However, these magnetometers suffer from a fundamental problem know...
Residual-<i>ZZ</i>-coupling suppression and fast two-qubit gate for Kerr-cat qubits based on level-degeneracy engineering
Building large-scale quantum computers requires an interqubit-coupling scheme with a high on–off ratio to avoid unwanted crosstalk coming from residual coupling and to enable fast multi-qubit operatio...
Lowering the coercive field of van der Waals ferroelectric NbOI2 with photoexcitation
Polarization switching in van der Waals ferroelectric materials driven by an electric field remains robust even at the atomic layer limit, paving the way for advances in the miniaturization and integr...
Toward model-free temperature diagnostics of warm dense matter from multiple scattering angles
Warm dense matter plays an important role in astrophysical objects and technological applications, but the rigorous diagnostics of corresponding experiments is notoriously difficult. In this work, we...
Synthesizing spin–orbit couplings and symmetry-protected topological phase in acoustic metamaterials
Spin–orbit couplings (SOCs) underlie several key concepts of topological matter. However, acoustic waves lack intrinsic spin and SOCs, which makes some topological phases impossible. We develop in the...
Quantum anomalous Hall effect for metrology
The quantum anomalous Hall effect (QAHE) in magnetic topological insulators offers great potential to revolutionize quantum electrical metrology by establishing primary resistance standards operating...
