Arqon: A suite of control applications enabling a reliable quantum network

Quantum Physics [Submitted on 9 Apr 2026] Arqon: A suite of control applications enabling a reliable quantum network Scarlett Gauthier, Thomas R. Beauchamp, Stephanie Wehner A quantum network's purpose is to enable users to execute applications on end nodes. This requires the network to provide the service of creating entangled links between those nodes. Users of mature networks, such as the internet or the telephone network expect accepted service demands to be met reliably. We first define reliability requirements that extend classical computer network concepts to quantum network service delivery. We then introduce Arqon, a suite of control applications designed to deliver reliable service in centrally controlled quantum networks. We demonstrate through both analytic and numerical evaluation that Arqon satisfies all reliability requirements for accepted demands. These evaluations consider static network topologies. We provide a complete Python implementation and perform complexity analysis showing that admission control scales as O(k^3) in the number of incoming demands k and schedule computation scales as {O(N^3)} in the number of accepted demands to schedule N.
