Summary
Adds support for
AnnotatedOperation.params
and, leveraging that, fixes some issues when controlling standard gates that are parameterized. Closes #10311, #10697 and #12135.Since this PR also changes
AnnotatedOperation
it's probably too large for a backport?Details and comments
AnnotatedOperation.params
is a proxy to tobase_op.params
, if it exists. If thebase_op
has noparams
, returns an empty list (as discussed with the team offline).annotated
argument inGate.control
now isNone
per default, which allows to set it toTrue
for gates that cannot be eagerly synthesized. A test for each gate that failed previously is added.S/Sdg
gates didn't returnCS/CSdg
gates for a single control, that's also been fixed.This is an automatic backport of pull request #12752 done by [Mergify](https://mergify.com).
