A new transpiler pass, :class:`.ContractIdleWiresInControlFlow`, is available from
|
|
:mod:`qiskit.transpiler.passes`. This pass removes qubits from control-flow blocks if the
|
|
semantics allow this, and the qubit is idle throughout the control-flow operation. Previously,
|
|
the routing stage of the preset pass managers might have done this as an accidental side-effect
|
|
of how they worked, but the behavior is now more properly placed in an optimization pass.
