+# Quantum Application Model Library
+
+- [Features](#features)
+- [Installation](#installation)
+- [How to Use](#how-to-use)
+- [Application List](#application-list)
+
+**Q**uantum **A**pplication **M**odel Library (QAML) is a collection of out-of-box practical quantum algorithms, it is developed by [Institute for Quantum Computing at Baidu](https://quantum.baidu.com/), and aims to be a "supermarket" of quantum solutions for industry users. Currently, models in QAML have covered popular areas listed below:
+
+- Artificial Intelligence
+- Medicine and Pharmaceuticals
+- Material Simulation
+- Financial Technology
+- Manufacturing
+- Data Analysis
+
+QAML is implemented on Paddle Quantum, a quantum machine learning platform, which can be found at https://qml.baidu.com and https://github.com/PaddlePaddle/Quantum.
+
+## Features
+
+- Industrialization: 10 models closely follow the 6 major industrial directions, covering hot topics such as artificial intelligence, chemical materials, manufacturing, finance, etc.
+- End-to-end: Linking the whole process from application scenarios to quantum computing and solving the last mile of quantum applications.
+- Out-of-box: No special configuration is required, the model is called directly by the Paddle Quantum, eliminating the tedious installation process.
+
+## Installation
+
+QAML depends on the `paddle-quantum` package. Users can install it by pip.
+
+```shell
+pip install paddle-quantum
+```
+
+For those who are using old versions of Paddle Quantum, simply run `pip install --upgrade paddle-quantum` to install the latest package.
+
+QAML locates in Paddle Quantum's GitHub repository, you can download the zip file contains QAML source code by clicking [this link](https://github.com/PaddlePaddle/Quantum/archive/refs/heads/master.zip). After unzipping the package, you will find all the models in the `applications` folder in the extracted folder.
+
+You can also use git to get the QAML source code.
+
+```shell
+git clone https://github.com/PaddlePaddle/Quantum.git
+cd Quantum/applications
+```
+
+You can check your installation by going to the `handwritten_digits_classification` folder under `applications` and running
+
+```shell
+python vsql_classification.py --example.toml
+```
+
+The installation is successful once the program terminates without errors.
+
+## How to Use
+
+In each application model, we provide Python scripts that can be run directly and the corresponding configuration files. The user can modify the configuration file to implement the corresponding requirements.
+
+Take handwritten digit classification as an example, it can be used by executing `python vsql_classification.py --example.toml` in the `handwritten_digits_classification` folder. We provide tutorials for each application model, which allows users to quickly understand and use it.
+
+## Application List
+
+*Continue update*
+
+Below we list instructions for all applications available in QAML, newly developed applications will be continuously integrated into QAML.
+
+1. [Handwritten digits classification](./handwritten_digits_classification/introduction_en.ipynb)
+2. [Molecular ground state energy & dipole moment calculation](./lithium_ion_battery/introduction_en.ipynb)
+3. [Text classification](./text_classification/introduction_en.ipynb)
+4. [Protein folding](./protein_folding/introduction_en.ipynb)

+
+量子应用模型库（**Q**uantum **A**pplication **M**odel **L**ibrary, QAML）是一个开箱即用的实用量子应用模型集合，它由[百度量子计算研究所](https://quantum.baidu.com/)研发，旨在成为企业用户的量子解决方案“超市”。目前，QAML 中的模型已经覆盖了以下领域：
+
+- 人工智能
+- 医学制药
+- 材料模拟
+- 金融科技
+- 汽车制造
+- 数据分析
+
+QAML 基于量桨这一量子机器学习平台实现，关于量桨的内容可以参考 https://qml.baidu.com 和 https://github.com/PaddlePaddle/Quantum 。
+
+## 特色
+
+- 产业化：10 大应用模型紧贴 6 大产业方向，涵盖人工智能、化工材料、汽车制造、金融套利等热点话题。
+- 端到端：打通应用场景到量子算法的全流程，解决量子应用的最后一公里问题。
+- 开箱即用：无需特殊配置，通过量桨直接完成模型调用，省去繁琐安装环节。
+
+## 安装
+
+QAML 依赖于量桨（ `paddle-quantum` ）软件包。用户可以通过 pip 来安装：
+
+```shell
+pip install paddle-quantum
+```
+
+对于那些使用旧版量桨的用户，只需运行 `pip install --upgrade paddle-quantum` 即可安装最新版量桨。
+
+QAML 的内容在 Paddle Quantum 的 GitHub 仓库中，用户可以通过点击[此链接](https://github.com/PaddlePaddle/Quantum/archive/refs/heads/master.zip)下载包含 QAML 源代码的压缩包。QAML 的所有模型都在解压后的文件夹中的 `applications` 文件夹里。
+
+用户也可以使用 git 来获取 QAML 的源码文件。
+
+```shell
+git clone https://github.com/PaddlePaddle/Quantum.git
+cd Quantum/applications
+```
+
+用户可以进入到 `applications` 下的 `handwritten_digits_classification` 文件夹中，然后运行以下代码来检查安装是否成功。
+
+```shell
+python vsql_classification.py --example.toml
+```
+
+如果上面的程序没有报错、成功运行的话，则说明安装成功了。
+
+## 如何使用
+
+在每个应用模型中，我们都提供了可以直接运行的Python脚本和相应的配置文件。用户可以修改配置文件来实现对应的要求。
+
+以手写数字识别为例，用户可以通过执行 `handwritten_digits_classification` 中的 `python vsql_classification.py --example.toml` 命令来快速使用。我们为每个应用模型提供了教程，方便用户快速理解和上手使用。
+
+## 应用列表
+
+*持续更新中*
+
+我们列出了目前 QAML 的所有应用案例的教程，新开发的应用案例也会持续添加进来。
