• Rename the repository and migrate to the openqasm organization
• Migrate all code references from qss->qe and quantum systems software to quantum engine
• Update the readme
  • Remove the repository name migration notice added in Add basic information and notices to README. #209
• Update all internal production usages to migrate to the new name wherever used
• Update the internal repository to point to the updated references
