摘要

Abstract

An optimized quantum network design is demonstrated by realizing a state-multiplexing quantum light source via a dual-excitation configuration technique. This approach optimizes the usage of the finite wavelength spectrum

facilitating the efficient expansion of entanglement-based fully-connected quantum networks across multiple users.
