Researchers from Italy have created a new way to make quantum computers more secure using glass. This breakthrough could help keep our data safe as quantum computers get more powerful.

In the world of technology, quantum computers are getting stronger every day. But this means that many current encryption methods might become vulnerable soon. One solution is called quantum cryptography, which uses the laws of physics to keep data secure. However, making quantum communication practical requires small devices that can accurately read delicate quantum signals carried by light.

A team of researchers from the University of Padua, Politecnico di Milano, and the CNR Institute for Photonics and Nanotechnologies has found a new approach using an unexpected material: borosilicate glass. They created a high-performance quantum coherent receiver built directly inside glass using femtosecond laser writing.

This method delivers low optical loss, stable performance, and compatibility with existing fiber-optic systems, making it important for moving quantum technologies beyond lab experiments.
