A Digital Twin of Atomic Ensemble Quantum Memory Experiments Based on an Effective Quantum Channel Description

Advanced Quantum Technologies, Volume 9, Issue 2, February 2026.
A tool to model ensemble‐based atomic quantum memory experiments using the quantum channel formalism is presented, incorporating realistic loss and noise effects. It provides a digital twin of state‐of‐the‐art memories and demonstrates its applicability through a simulation of a memory‐assisted quantum token protocol. The framework is easily extendable

Bandgap Engineering On Demand in GaAsN Nanowires by Post‐Growth Hydrogen Implantation

Small, Volume 22, Issue 7, 2 February 2026.
The GaAsN bandgap in the GaAs/GaAsN core–shell nanowire shifts to lower energy for increasing N concentrations. By post‐growth H implantation the GaAsN bandgap is moved to a higher GaAs‐like energy through the formation of N–H complexes. By thermal annealing, these complexes can be partially dissolved, allowing to tune the GaAsN bandgap over a range of

Coherent Spin Waves in Curved Ferromagnetic Nanocaps of a 3D‐Printed Magnonic Crystal

Small, Volume 22, Issue 7, 2 February 2026.
A nanoprinted 3D magnonic woodpile crystal is measured by microresonator ferromagnetic resonance. Micromagnetic simulations are performed to analyze and visualize the detected coherent spin‐wave modes along the nickel‐coated tubes and caps for various field angles. The woodpile exhibits an unexpected phase evolution and robust edge modes.

Narrow-linewidth erbium-doped fibre lasers

, 1991
This thesis describes research towards narrow-linewidth and single-longitudinal-mode erbium-doped fibre lasers operating on the 1.55µm region. The work is concerned with the physics and technology of narrow-linewidth fibre lasers. Factors which affect the spectral width and number of modes oscillating in an erbium-doped fibre laser are described, with ...

Enhanced Refractive Index Sensitivity of Linearly Assembled Gold Nanoantennae for Biosensing Applications

Small, Volume 22, Issue 9, 12 February 2026.
This study presents scalable methods for fabricating linear arrays of gold nanoparticles using template‐assisted self‐assembly. These supracolloidal structures show strong polarization‐dependent plasmonic responses for biosensing. Using antibody detection for Tumor Necrosis Factor‐Alpha (TNF‐α) as a proof‐of‐concept, the assemblies exhibit up to five ...
