Recent advances in quantum information science enabled the development of quantum communication network prototypes and created an opportunity to study full-stack quantum network architectures. The same way classical network simulators helped build the classical Internet, quantum network simulations are expected to play an increasingly important role in designing future quantum networks that scale to long distances and large number of hosts, and meet the latency, reliability and security needs of emerging applications. This talk introduces SeQUeNCe, a comprehensive, customizable quantum network simulator. Our modularized framework is suitable for simulation of quantum network prototypes that capture the breadth of current and future hardware technologies and protocols. We have implemented a comprehensive suite of network protocols and demonstrate the use of SeQUeNCe by simulating a quantum key distribution network, a teleportation network, and a metropolitan quantum network in the Chicago area consisting of nine routers equipped with quantum memories. SeQUeNCe is available as open source on GitHub. In this tutorial, we will present the design and architecture of SeQUeNCe followed by a live demonstration and hands-on exercises.
