Tutorials

This repository also holds notebooks for tutorials used in presentations and workshops.

• Compilation with BQSKit combined with error mitigation from mitiq
• Programming neutral-atom analog quantum processors with Bloqade
• The Weisfeiler-Lehman Test with Pulser

The neutral-atom-tutorial directory contains also tutorials from Pulser documentation:
