Quantum Internet Takes a Major Step Forward: Entangled Signals Transmitted Over Existing Fiber Networks
A key barrier to the quantum internet—building secure, large-scale quantum communication networks—has been the need for specialized infrastructure. Researchers have now demonstrated that quantum signals, including entangled particles of light, can be successfully transmitted across standard telecommunications fiber in real urban environments.
This breakthrough proves that existing fiber optic lines can support the delicate quantum states required for entanglement swapping and multi-node networks, without needing entirely new infrastructure. It marks progress toward entanglement distribution over metropolitan distances using current telecom tech, paving the way for quantum-secure communications, distributed quantum computing, and a future quantum internet that integrates with today’s networks.
By leveraging proven fiber infrastructure, this work significantly reduces deployment costs and timelines for practical quantum networking.
