How does this achievement contribute to the development of a practical quantum internet, and what challenges remain?

This experiment demonstrates the feasibility of building a quantum internet using existing telecommunications infrastructure, overcoming previous limitations requiring specialized, costly equipment. By maintaining quantum coherence in a real-world setting, the research opens the door for widespread implementation of quantum communication, paving the way for enhanced security and future applications. This success builds on prior work achieving transmission over even greater distances (372 miles), but this research stands out due to the use of standard, commercially available infrastructure under real-world conditions.
