Fix a bug in the multi-controlled rotation circuit methods :meth:`.QuantumCircuit.mcrx`,
|
|
:meth:`.QuantumCircuit.mcry`, and :meth:`.QuantumCircuit.mcrz`, when the user provides an unbounded parameter,
|
|
as well as when calling :meth:`.RXGate.control`, :meth:`.RYGate.control` or :meth:`.RZGate.control` where the
|
|
rotation angle is a :class:`.ParameterExpression`.
|
|
Previously, the user got an error that this gate cannot be synthesized with unbound parameter,
|
|
and now these multi-controlled rotation circuits can be synthesized without raising an error.
