A groundbreaking Chinese research team has advanced the frontiers of quantum direct communication by introducing a long-distance, large-scale, and scalable fully connected theoretical framework. They have triumphantly established a 300-kilometer-scale communication network spanning four nodes. Leveraging dual-pumped optical parametric down-conversion, this technology has engineered a highly resilient quantum entanglement distribution system, boasting quantum state fidelity exceeding 85% between nodes and a theoretical communication rate of several bits per second.
