QiskitSpecStage

class QiskitSpecStage

Bases: CircuitSpecStage

SpecStage that converts Qiskit QuantumCircuit(s) into MetaCircuit(s).

Accepts three input shapes:

• A single QuantumCircuit → one-element batch

• A Sequence[QuantumCircuit] → indexed by position

• A Mapping[str, QuantumCircuit] → indexed by key name

Qiskit measure instructions are converted to probs() on the measured wires. If the circuit has no measurements, all wires are measured by default (with a warning).

Qiskit Parameter objects flow through directly — the migrated pipeline is Qiskit-native, so there’s no sympy detour. ParameterExpression objects (e.g. 2 * theta) are preserved on the resulting DAG, and resolved by ParameterBindingStage at bind time.
