AI Commentary
This review pulls together the latest teleportation experiments across photons, ions and solid‑state qubits, showing how each platform is closing the distance gap that has long limited quantum networking. By framing those results within emerging repeater architectures, it highlights a concrete path toward the long‑promised quantum internet rather than leaving the concept in theoretical limbo. Readers should note that while scalability remains a hurdle—especially regarding loss‑tolerant error correction—the article makes clear which technical bottlenecks are now being tackled and where near‑term commercial services may first appear.

Summary
Quantum networks play a pivotal role in quantum information science, which not only provide a secure communication platform for remote access to quantum computers but also serve as the strategic core for achieving large-scale quantum information processing, forming the foundational infrastructure for the future global-scale quantum internet. Quantum teleportation, which enables the transmission of unknown quantum states over long distances by employing quantum entanglement together with classical communication, is essential for the distribution of quantum resources in the construction of the global-scale quantum internet. To realize a global-scale quantum internet, quantum repeater protocols represent one of the most promising approaches for enabling quantum communication between any nodes. This concise review presents representative experimental demonstrations of quantum teleportation for constructing quantum networks across different physical platforms. Along this trajectory, the review discusses current challenges, open issues, and future perspectives toward scalable and practical quantum internet.
