Launch Lab

​
Starting an Instance

From your account page, select a compute profile and click Launch New Instance to start your quantum environment. Users will have access to all available compute profiles, which range from basic CPU instances (2-8 vCPUs with 4-25 GB RAM) to high-performance GPU instances (H100, A100, GH200). Some compute profiles, particularly GPU instances, consume qBraid credits based on usage (charged per minute). Paid subscription tiers provide additional benefits including higher disk storage limits and compute hours for extended development and research workflows.

Depending on its size, pulling an image may take up to 2 minutes for the first time. The next time you launch Lab, it will load much more quickly.

​
Stopping Lab

To stop your running Lab instance:
  1. Navigate to your account dashboard
  2. Click Stop Running Server to stop the running instance
stop_lab_new_account
Stopping your server will not delete your data, but will stop it from running and consuming compute hours.

Lab interface

Once your image is pulled, you will be taken to the qBraid Lab interface. Here are a few helpful resources to get started:
  • Interactive tour: Click Start Tour (pop-up at first launch, or Help drop-down) to begin a guided tour of all of the Lab extensions and their key features.
  • qBraid tutorials: The qbraid-tutorials directory (left-sidebar FILES tab) contains examples and tutorials for a wide range different quantum software packages. Many of the notebooks contain qBraid instructions and are runnable using the Python 3 [Default] environment.
  • Help drop-down: The top-bar menu Help drop-down contains links to qBraid user guides, demos, and other reference materials.
