Clifford Data Regression

Clifford data regression (CDR) is a learning-based quantum error mitigation technique in which an error mitigation model is trained with quantum circuits that resemble the circuit of interest, but which are easier to classically simulate [6, 19].

The CDR workflow in Mitiq is fully explained in the What happens when I use CDR? section.

Below you can find sections of the documentation that address the following questions:

• How do I use CDR?
• When should I use CDR?
• What additional options are available in CDR?
• What happens when I use CDR?
• What is the theory behind CDR?

A simple tutorial using CDR can be found on the How do I use CDR? page.
