UV Laser-Induced Creation of Coherent V2 Spin Defects in 4H-SiC Nanopillars

UV laser pulses create V2 spin centers in commercial 4H-SiC nanopillars with 11× higher yield, preserving near-lifetime-limited optical linewidths and achieving 3.6 ms spin coherence via dynamical decoupling—enabling scalable quantum network nodes.

Quantum Networks: Spatial-Mode Mixing Induces 'Hyperloss' Exceeding 100%

Researchers at Universität Hamburg found just 8% spatial-mode mismatch destroys a 5.8dB squeezed state entirely—a 'hyperloss' exceeding 100%. Phase tuning of spatial modes recovered lost correlations, reducing 15% geometric mismatch to ~2.8% effective loss.
