# QuREKA Interfaces
**Understanding QuREKA System Structure**
All information and resources on the QuREKA platform are managed based on the **Workspace**.
- **Workspace-Based Information:** All menus in the left sidebar—including Dashboard, Quantum Server, and Quantum Jobs—display data specific to the currently selected workspace.
- **Resource Isolation:** Each workspace maintains its own independent API keys, credits, and quantum servers. When collaborating on different projects or with different teams, please ensure you switch to the appropriate workspace using the workspace switcher icon in the upper right corner before proceeding with your work.
# Dashboard
The Dashboard is the central hub of QuREKA, where you can manage Quantum Servers, handle subscription plans, and monitor job trends and lists at a glance.
By using the configuration button on the upper right, users can customize the dashboard with their preferred components (widgets). Each item’s position and size can be freely adjusted to create an optimized layout tailored to the user's needs.

### Key Dashboard Components
#### **Plan Summary**
- View and manage the current subscription plan of the workspace.
- For security and billing management, only the Workspace Owner has the authority to change the subscription plan.
#### **Credits Usage**
- Monitor the remaining credits and current usage status of the workspace in real-time to manage your budget effectively.
#### **API Key Management**
- Manage the unique API key assigned to each individual within the workspace.
- This key is mandatory for user authentication when submitting quantum jobs. Reissuance features are provided for security in case of key exposure.
#### **Quantum Server**
- Manage dedicated computational resources for quantum algorithm development.
- You can immediately create a Quantum Server via the **\[Create\]** button. Once created, you can start developing in the following environments:
- **Notebook**: A code-based development environment powered by JupyterLab.
- **Composer**: A GUI-based environment for designing quantum circuits using drag-and-drop functionality.
- **No-code**: A simplified development environment that requires no coding (scheduled for a future update).
Note: The available types and specifications (vCPU, RAM, GPU, etc.) of Quantum Servers depend on your current **Subscription Plan**.
#### **Job Trend**
- Provides a visual representation of the daily trend for quantum jobs executed within the workspace, helping users understand their usage patterns.
#### **Recent Jobs**
- Quickly check the list and status of the most recent jobs in the workspace.
- Click the **\[More\]** button to navigate to the **Quantum Jobs** tab for a detailed history of all tasks.
# Workspace
A Workspace is the fundamental unit for team collaboration and resource management. On the Workspace Management page, you can control basic information about the current workspace and manage participating members.
[](https://docs.qurea-dev.sdt.services/uploads/images/gallery/2026-02/3afT121INn.png)
### Workspace Information
This section provides essential details about the workspace. You can check the workspace name, creation date, and the current Owner.
### Member Management
This feature allows for the systematic management of users within the workspace. Administrators can freely adjust the member composition and permissions according to the nature of the project.
- **Inviting and Verifying Members:** You can invite new team members to collaborate by entering their email addresses. Through the invitation menu, you can check the list of sent invitations and monitor the real-time status of members pending acceptance.
- **User Permission Management:** You can set or change permissions for each member belonging to the workspace. This allows you to control the scope of resource access according to each member's specific role.
- **Member Removal:** You can remove members with whom collaboration is no longer required. Upon removal, all access rights to the resources within that workspace are immediately revoked.
# Quantum Server
The Quantum Server page allows you to manage dedicated computational resources for developing and simulating quantum algorithms. You can create servers, control their operational status, and access the development environment here.
### 1. Creating a Quantum Server
To establish a new development environment, you must first create a Quantum Server.
- **Creation Method**: Click the **\[+ Create\]** button at the upper right of the page.
- **Select Specifications (SPEC)**: First, select the server specifications (SPEC) you wish to use.
- **Note**: The available server types vary depending on your current Subscription Plan.
- **Enter Name**: Input a name for the server you are creating.
- **Credit Pre-deduction**: Upon accessing the Quantum Server after it starts, **credits will be pre-deducted** based on the server specifications. You can preview the amount of credits to be deducted on the screen during the creation process.
### 2. Quantum Server List
Displays a list of all created Quantum Servers along with their detailed information.
#### **SPEC (Server Specifications)**
