Add conversion transpiler pass from `c_if` to `IfElseOp`

Open jakelishman opened this issue 1 year ago • 2 comments

Summary

This is intended to be used to ease the transition from the old-style conditions to the new-style form. Backends may use it in their custom pipelines, so they can guarantee they only need to deal with one form.

A further classical optimisation may be to group IfElseOp blocks that share the same condition into a single operation, but this would likely be a separate pass, if added, or potentially be the domain of a separate part of the circuit-description/compilation/running pipeline.

Details

Fixes #8601.

Will need rebasing over #8627 and #8615 once they merge, as this depends on them, and currently includes their commits. I just can't look at my screen any more tonight to wait til it merges.

edit: This is now rebased.
