Dynamic Continuous Variable Quantum Key Distribution for Securing a Future Global Quantum Network
Advanced Quantum Technologies, EarlyView.The article explores securing a dynamic global quantum network using continuous variable QKD, proposing a unified three‐layer network architecture for integrating existing QKD networks. It evaluates secret key rates across various channels and introduces the link capacity as a metric for determining the optimum path for secret key distribution in a ...

Nonreciprocal Entanglement of Frequency‐Distinct Qubits
Advanced Quantum Technologies, EarlyView.This work demonstrates the first spatiotemporal superconducting metasurface for nonreciprocal entanglement between frequency‐mismatched qubits at millikelvin temperatures. Leveraging space‐time‐modulated Josephson field‐effect transistors (JoFETs), the platform enables unidirectional, spurious‐free quantum state conversion with high efficiency.

Low‐Loss Polarization‐Maintaining Router for Single and Entangled Photons at a Telecom Wavelength
Advanced Quantum Technologies, EarlyView.A novel electro‐optic routing of arbitrarily polarized single photons and, crucially, multi‐photon entangled states is demonstrated. Utilizing optics with near‐normal incidence and cross‐aligned electro‐optic crystals, low‐loss polarization‐maintaining routing is achieved with a minimal number of components.

Advanced Quantum Technologies, EarlyView.Coupling quantum light into optical single‐mode fibers is a strict requirement for quantum technological implementations. This work experimentally quantifies coupling efficiency of telecom single‐photons from circular Bragg grating cavities into silica fibers even equipped with 3D‐printed micro‐lenses.

Reactive Nanoparticle Composed Bilayers: An Alternate Route Toward the Production of Pt/Al Nanofoils
Small, EarlyView.Spark ablation‐assisted gas phase electrodeposition is an alternate route toward Pt/Al self‐propagation reactive system synthesis. Pt film morphology‐dependent reaction kinetics is a significant advantage. Low spark power and gas flow rate produce porous films and slow speeds, while high power and flow rate give three orders of magnitude faster ...

HiLAB: A Hybrid Inverse‐Design Framework
Small Methods, EarlyView.A hybrid inverse‐design framework (HiLAB) integrates truncated topology optimization, a Vision Transformer–based variational autoencoder, and Bayesian optimization to accelerate the design of complex photonic structures. By jointly optimizing geometry and physical parameters in a compact latent space, HiLAB reduces simulation cost by over tenfold and ...
