Quantum Frequency Conversion of Single Photons from a Tin-Vacancy Center in Diamond

Posted by klaurent Delft

Kavli Affiliate: Ronald Hanson | Summary:Diamond tin-vacancy (SnV) centers are promising candidates for building quantum network nodes. However, their native photon emission at 619 nm is incompatible with metropolitan-scale networks operating at low-loss telecom wavelengths. To address this, we demonstrate highly efficient, low-noise quantum frequency conversion (QFC) of 619 nm photons to the telecom S-band […]

POINTS-Reader: Distillation-Free Adaptation of Vision-Language Models for Document Conversion

Posted by klaurent Peking

Kavli Affiliate: Xuebing Wu| First 5 Authors: Yuan Liu, Yuan Liu, , , | Summary:High-quality labeled data is essential for training accurate document conversion models, particularly in domains with complex formats such as tables, formulas, and multi-column text. However, manual annotation is both costly and time-consuming, while automatic labeling using existing models often lacks accuracy […]

Infinity thick quasiconvexity and applications

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Miguel García-Bravo, Miguel García-Bravo, , , | Summary: We investigate geometric properties of a metric measure space where every function in the Newton–Sobolev space $N^1,infty(Z)$ has a Lipschitz representative. We prove that when the metric space is locally complete and the reference measure is infinitesimally doubling, the […]
