We explore a November 2025 milestone from Stuttgart, Saarbrücken, and Dresden where researchers teleported a photon's polarization state between two independent quantum dots. The breakthrough hinges on perfectly indistinguishable photons and quantum frequency conversion to enable entanglement swapping across fiber, advancing the dream of a secure quantum internet. We break down why quantum repeaters matter for long-distance QKD and distributed quantum computing, how the no-cloning theorem drives the need for this approach, and what the 70% success rate and real-world 36 km tests mean for moving from lab demos toward scalable, fault-tolerant quantum networks.
