 # iQuantum ![Project Status](https://img.shields.io/badge/Project-Beta%20Release-yellow) [![iQuantum Maven Build](https://github.com/Cloudslab/iQuantum/actions/workflows/maven.yml/badge.svg)](https://github.com/Cloudslab/iQuantum/actions/workflows/maven.yml)
 
 ##  A Toolkit for Modeling and Simulation of Quantum Computing Environments
+As quantum computers become increasingly accessible through cloud services and potentially extend to edge networks in the future, the demand for efficient resource management strategies is paramount to ensure the efficient utilization of quantum computing resources. However, the limitations of employing practical quantum computing resources and the lack of quantum environment modeling toolkits have hindered the design and evaluation of quantum resource management policies. To address this challenge, we propose iQuantum, a lightweight and versatile discrete-event modeling and simulation toolkit (based on CloudSim) for quantum computing environments. iQuantum provides a set of quantum computing entities that can be customized and extended to support a wide range of different hybrid quantum computing environments, supporting research in quantum resource management (e.g., task scheduling, backend selection, hybrid task orchestration), designing and prototyping of quantum computing systems.

 1. **Modeling**: The user defines the quantum computing environment (e.g., quantum datacenters, quantum computers, quantum tasks, and quantum brokers) using the iQuantum entities.
    - Quantum tasks and quantum nodes can be modeled manually or automatically by importing from dataset (.csv), which can be generated from QASM files for quantum tasks (e.g., using [MQT Bench](https://www.cda.cit.tum.de/mqtbench/)) and system calibration datasheet (e.g., from [IBM Quantum](https://quantum-computing.ibm.com/lab/docs/iql/manage/systems/configuration)).
    - Resource management policies (scheduling, mapping, backend selection, and offloading) can be customized by extending the corresponding classes (in `org.iquantum.policies` package).
