From Sci-Fi to Reality: Vacuum Tubes Could Revolutionize Quantum Networking

A new approach for quantum networks involves using vacuum sealed tubes with spaced-out lenses to transport quantum data via photons over long distances. This method, developed by scientists at the University of Chicago and collaborators, aims to enable secure, high-capacity quantum communication across vast distances.

Quantum computers offer powerful ways to improve cybersecurity, communications, and data processing, among other fields. To realize these full benefits, however, multiple quantum computers need to be connected to build quantum networks or a quantum internet. Scientists have struggled to come up with practical methods of building such networks, which must transmit quantum information over long distances.
