Abstract
We describe the development of the NetQStack Simulator, a network-integrated simulation framework designed to evaluate distributed quantum computing (DQC) within data center environments. Our approach strictly models the network topology, classical control plane, and quantum data plane required to execute distributed quantum workloads. The simulator models classical and physical-layer protocol synchronization, schedules sub-circuit executions on individual Quantum Processing Units (QPUs), and routes entanglement generation requests across Bell State Measurement (BSM) nodes. With the ability to use external network-aware circuit partitioning software, and interface with an intelligent quantum network controller, this architecture enables researchers to execute fully distributed algorithms while rigorously evaluating the impact of network latency, routing heuristics, and control-plane overhead. Our early results demonstrate that a network-integrated approach provides useful insights when assessing the performance and scalability of distributed quantum algorithms.
