Their new stabilization method overcomes disruptions, keeping the network running smoothly and securely.

Quantum Breakthrough: First Entangled Signal Over Commercial Network

Researchers from the Department of Energy’s Oak Ridge National Laboratory (ORNL), EPB of Chattanooga, and the University of Tennessee at Chattanooga have successfully transmitted an entangled quantum signal over a commercial fiber-optic network. This achievement marks the first time multiple wavelength channels and automatic polarization stabilization have been used together — without any network downtime.
