Eurofiber and Delft Networks deployed entanglement-ready dark fiber connecting Rotterdam and Delft in a closed-loop configuration.

Eurofiber and Delft Networks have deployed dark fiber between Rotterdam and Delft, according to Data Center Dynamics. The source explicitly describes the deployment as a closed-loop configuration.

The infrastructure is described as entanglement-ready, and the article identifies quantum networking as its purpose. This is a fiber-network deployment, not a disclosure of additional GPUs, quantum processors, or data-center electrical capacity.

The supplied excerpt does not report a demonstrated entanglement connection, operational quantum service, route length, transmission performance, or customer contract. “Entanglement-ready” therefore should not be expanded into a claim that end-to-end quantum operation has already been demonstrated.
