The ibmqx-backend-information repo contains information useful to IBM Q experience users

The backends directory contains information about the IBM Q experience backends. At the moment there are documents for available hardware backends. Soon, we will update this to include specifications on various simulation backends. We anticipate the simulation backends to be community-driven as well, and we welcome the inclusion of new ones that can plug into our interface.

For research papers, we encourage authors to acknowledge the IBM Q experience with
