Qubit to stim

SquinQubitToStim

Bases: RewriteRule

NOTE this require address analysis result to be wrapped before using this rule.

rewrite_ControlledGate 

rewrite_ControlledGate(
    stmt: ControlledGate,
) -> RewriteResult

Rewrite controlled gate nodes to their stim equivalent statements. Address Analysis should have been run along with Wrap Analysis before this rewrite is applied.
