Summary

Story summary

Researchers from the University of Padua, the Politecnico di Milano, and the CNR Institute for Photonics and Nanotechnologies developed a quantum coherent receiver using borosilicate glass.
Femtosecond laser writing yielded low optical loss for quantum communication.
In a simulated 9.3-km fiber link, it achieved record secure random bit generation rate of 42.7 Gbit/s and a 3.2 Mbit/s secret-key rate; the study notes glass's stability and cost-effectiveness for scalable quantum networks.
