## What it is
SimQN is a discrete-event network-layer simulator for quantum networks, written in Python with optional Cython acceleration. It supports large-scale investigations of QKD protocols, entanglement distribution, and quantum routing algorithms.

## Use cases
- simulate quantum network protocols
- evaluate QKD protocol performance
- test entanglement distribution algorithms
- research quantum network routing
- model large-scale quantum internet topologies
- run parallel quantum network simulations

## When to choose
- you need a Python-based, easy-to-extend quantum network simulator
- you are researching network-layer quantum protocols like QKD or entanglement routing
- you want a simulator with academic track record and active development

## When to avoid
- you need physical-layer qubit-level simulation rather than network-layer modeling
- you need a production quantum networking stack rather than a research simulator

## Facets
- artifact type: library
- maturity: active
- function: simulation, networking
- domain: quantum-computing, networking, simulation
- platform: python, cross-platform
- tags: quantum-network, quantum-internet, discrete-event-simulation, qkd, entanglement-distribution, quantum-routing, cython-acceleration, research
