Polarization‐Improved Bidirectional‐Pump Atomic Magnetometer Based on Spin‐Decoupled Metasurface

Advanced Science, EarlyView.
The polarization‐improved bidirectional‐pump atomic magnetometer based on spin‐decoupled metasurface has been experimentally demonstrated. The system, based on a metasurface, successfully realizes precise control of atomic spin polarization. The research not only offers a novel technique for designing high‐performance optically pumped atomic ...

High‐Speed Design of Multiplexed Meta‐Optics Enabled by Physics‐Driven Self‐Supervised Network

Advanced Science, EarlyView.
A physics‐driven self‐supervised network (PDSS‐Net) is proposed for high‐speed, iteration‐free design of multiplexed meta‐optics. By learning a direct mapping from holographic targets to all meta‐atom structures, PDSS‐Net achieves a 1000× speedup over traditional optimization methods in designing 2K RGB meta‐holograms.

Reversing Hydrogen‐Related Loss in α‐Ta Thin Films for Quantum Device Fabrication

Advanced Science, EarlyView.
α‐Tantalum is one of the best materials for superconducting quantum computers because of its stable, low microwave‐loss oxide. However, excessive amounts of hydrogen can enter the material during fabrication. This study shows that hydrogen degrades quantum device performance, while annealing the device in ultra‐high vacuum removes hydrogen and fully ...

Circular Polarimetric Imaging with a Metamaterial Integrated Long‐Wavelength Infrared Focal Plane Array

Advanced Science, EarlyView.
A quantum well infrared photodetector based long‐wavelength infrared division‐of‐focal‐plane‐array circular polarimeter featuring a 320 × 256 pixel array integrated with a chiral meta‐mirror structure array is established. The device achieves a circular polarization extinction ratio of 5.67, a 9.13‐fold enhancement in responsivity, a noise equivalent ...
