v0.20.0

Summary

This milestone focused on updating our support for numpy (1.23), adding a tutorial demonstrating the learning-based PEC workflow, and scoping out what device/noise calibration might look like as part of Mitiq. Additionally identity insertion has been added as a noise-scaling technique available for mitigation protocols such as zero-noise extrapolation. Expect more documentation of this feature in future releases. Big thanks to @purva-thakre for getting this in Mitiq!

There are also some minor bug fixes, documentation updates, and a new example contributed by @nickdgardner as well!
