Multiverse: A Simulator for Evaluating Entanglement Routing in Quantum Networks

2025-12-28

AI Summary

To address the low evaluation efficiency of entanglement routing and the difficulty of cross-paradigm comparison in dynamic heterogeneous quantum networks, this paper introduces MQNS—a lightweight discrete-event simulation framework. Methodologically, MQNS features: (1) a unified qubit lifecycle model coupled with an integrated link architecture model, enabling runtime-configurable entanglement purification, swapping, quantum memory management, and routing policies; and (2) a modular, minimalist design that decouples hardware and protocol paradigms, ensuring fair and reproducible multi-protocol benchmarking. The framework significantly accelerates entanglement routing algorithm evaluation, supports quantum internet protocol design, and facilitates verification of hardware abstraction layers. As an open-source, reproducible, and standardized evaluation platform, MQNS advances quantum network research by enabling rigorous, comparable, and scalable performance analysis across diverse quantum networking scenarios.

Abstract

We present MQNS, a discrete-event simulator for rapid evaluation of entanglement routing under dynamic, heterogeneous configurations. MQNS supports runtime-configurable purification, swapping, memory management, and routing, within a unified qubit lifecycle and integrated link-architecture models. A modular, minimal design keeps MQNS architecture-agnostic, enabling fair, reproducible comparisons across paradigms and facilitating future emulation.
