Add `error_mitigation` and `sharpen` configurations to IonQ backend #470

splch · 2023-07-24T16:54:04Z

Description

Error Mitigation
The IonQ quantum computation platform provides an error mitigation option, which can be specified in the backend configuration. To enable error mitigation, set the error_mitigation field in the BackendConfig object to a map containing debias: true, as follows:

config["error_mitigation"]["debias"] = true;

Post Example:

"error_mitigation": {
  "debias": true
}

Sharpen
The IonQ quantum computation platform provides a sharpening feature to enhance the computation precision. This feature can be controlled by setting the sharpen field in the BackendConfig object, as follows:

config["sharpen"] = true;

Query Example:

...&sharpen=true

Thanks for these updates, @splch. Should these changes be paired with any updates to ionq.config to activate the changes? In any case, I'll also post a few suggested updates for my review comments below. Let me know if they meet your intentions.

It would be nice to also update the IonQ section of the documentation (in docs/sphinx/using/hardware.rst) to explain how/when/why the user should use --ionq-debias and --ionq-sharpen. If that's too much trouble, then you could put it in this comment and I could update it after this PR gets merged.

I merged from main and applied updates based on my review comments. (Hopefully that's ok...we've got code cutoff for 0.5.0 coming very quickly now, and I figured it would be best to push this along.)

I also ran all the IonQ tests that the nightly integration test would run, and they passed.
