Argonne demonstrates software-orchestrated quantum-network applications with 12-hour stable entanglement distribution over deployed campus fiber
An arXiv preprint (2511.01247, submitted 2025-11-03; first author Md. Shariful Islam, Argonne National Laboratory) reports an experimental demonstration on the Argonne Quantum Network (ArQNet) testbed: continuous, stable entanglement distribution between remote sites running for 12 hours across the Argonne campus over deployed telecom fiber, orchestrated by software-defined-networking principles that automate quantum-communication experiments. The work is a deployed real-network result, not a simulation.
A DOE national-lab quantum-network testbed sustaining 12 hours of stable remote entanglement distribution over deployed telecom fiber is a credible infrastructure milestone for the networking domain, clearing section 7.3(a) on national-lab affiliation as a measured deployed result. It sits in the mid band: meaningful for quantum-networking practitioners but early-stage and not yet of broad cross-sector materiality.
Software-orchestrated automation of a deployed quantum network moves the field from one-off physics demonstrations toward operable testbeds, a prerequisite for repeatable benchmarking and eventual multi-node quantum-network services; commercial relevance depends on whether national-lab testbeds standardize interfaces that vendors can build to.
