TOKEN=a0ad9scjo23u0kaslodi
URL=https://auth.quantum-computing.ibm.com/api
HUB=ibm-q
GROUP=open
PROJECT=main
SEED=12345678

Execution

Open the desired notebook from ./notebooks in e.g. VSCode (with appropriate jupyter extensions installed). Or run

just notebook xyz # do not include the ipynb extension!

to run the notebook xyz.ipynb in a browser.

• Job monitoring/cancellation: https://quantum-computing.ibm.com/jobs.

NOTE: Queued jobs in the cloud can sometimes take hours. Keep the size of experiments small (e.g. small circuit sizes, small numbers of samples, small number of shots) or cancel + delete old jobs, that are still pending and which are no longer needed.
