# QuREKA-Lab
Quantum Server
QuREKA Lab is a **dedicated quantum algorithm development environment** established by creating a Quantum Server.
- **Server-Based Environment**: You can access the lab by clicking the **\[Open\]** button in the Quantum Server list. It provides a development interface powered by JupyterLab.
- **Customized Specifications**: The development environment is configured precisely according to the hardware specifications (CPU, RAM, GPU, and Storage) you selected during the Quantum Server creation step.
- **Consistent Development Experience**: Based on high-performance computing resources allocated according to your subscription plan, you can reliably perform complex quantum simulations and algorithm designs.
# Notebook
QuREKA Lab provides a powerful Python development environment based on JupyterLab, supporting an efficient workflow through dedicated extensions and AI-powered tools optimized for quantum algorithm development.

### Key Features
- **Intuitive Design**: Build circuits by placing gates and efficiently manage logical structures using slicers and barriers.
- **Real-time Simulation**: Instantly updates output states and histograms for up to 16 qubits using GPU acceleration upon any design modification.
- **Visual Analysis**: Provides a clear understanding of qubit phase changes and dynamic state flows through graphics and animations.
- **Multi-Environment Support**: Convert designed circuits into over 10 different quantum languages, such as Qiskit and Cirq, or directly submit them to actual QPU and simulator resources.
# Git Management
Notebook provides a built-in Git panel that allows you to clone repositories, pull the latest changes, and push your work to a remote repository.
### 1. Opening the Git Panel
Click the **Git icon** in the left sidebar to open the Git panel.

### 2. Cloning a Repository
You can bring an existing remote repository into your workspace.
- Click **Clone a Repository** in the **Git panel**.
- In the dialog that appears, enter the repository URL.
- Leave the two option checkboxes at their default values without modification.
- **Include submodules**: Clones any Git submodules embedded in the repository along with the main repository. Check this if the project includes externally linked repositories.
- **Download the repository**: Downloads the files only, without Git history or branch information. Use this if you only need the code without version control.
- Click **Clone** to begin. The cloned repository will appear in the file browser on the left.
