Multiverse is a quantum network simulator designed to streamline the comparative evaluation of entanglement routing under dynamic and heterogeneous network conditions. It addresses the need for a unified, flexible framework for rapidly prototyping and benchmarking a wide range of entanglement distribution strategies and quantum network architectures. The simulator supports systematic exploration of routing algorithms, swapping strategies, purification schedules, and qubit/resource management across diverse network scenarios. This artifact installs and runs MQNS software in a FABRIC node.
