Rapid Quantum Network Simulation Design with a Path to Scalable Execution

As quantum networking grows in importance, its study is of interest to an ever wider community. Several simulation frameworks allow for testing such systems on commodity hardware, but can be difficult to work with and performance-limited due to their predominantly serial nature. The SeQUeNCe simulator addresses the latter issue, though has not been proven to work well across architectures or larger scales. For the former concern, we introduce BISQIT, a block-diagramme-based framework that models in terms of distinct components and the data flows between them. This provides a simple and modular approach to experimental design that allows for rapid iteration with a library of reusable parts. We demonstrate the flexibility of its design for prototyping and show a path for how to migrate designed experiments to SeQUeNCe for production-scale testing. Our results show the simplicity of the BISQIT model and provide new insight into SeQUeNCe’s scalability behaviour using ORNL’s Frontier.
