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

Kavli Affiliate: Ronald Hanson | First 5 Authors: Julia M. Brevoord, Julia M. Brevoord, , , | 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, […]

Kwai Keye-VL 1.5 Technical Report

Kavli Affiliate: Jing Wang | First 5 Authors: Biao Yang, Biao Yang, , , | Summary: In recent years, the development of Large Language Models (LLMs) has significantly advanced, extending their capabilities to multimodal tasks through Multimodal Large Language Models (MLLMs). However, video understanding remains a challenging area due to the dynamic and information-dense nature […]

Infinity thick quasiconvexity and applications

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 […]
