Story summary

Engineers at the University of Pennsylvania created the "Q-chip," which transmits quantum signals over existing fiber-optic cables using standard Internet Protocol (IP).
This innovation could enable a transformative "quantum internet" by integrating quantum communication with commercial networks.
The Q-chip maintains quantum data integrity during transmission and achieved over 97% fidelity on Verizon's fiber network.
Its silicon design supports mass production for network expansion.
However, amplifying quantum signals without losing entanglement remains a challenge.
