I think this call to the add_qiskit_data method is wrong.

The if_qc QuantumCircuit gives an empty list upon if_qc.qregs. Thats why I'm creating circuits with new register names.

Running into trouble when trying to append the data from the if_qc to the circuit with the named registers (new_if_qc).

print(circ.qubits, circ.bits)
print(if_box.get_circuit().qubits, if_box.get_circuit().bits)
print(qubits)
print(bits)

prints

[q105[0], q105[1]] [c3[0], c3[1]]
[q105[0], q105[1]] [c3[0], c3[1]]
[q105[1]]
[c3[0]]

So the box has 2 qubits and 2 bits, but in add_circbox, args=qubits + bits only provides 1 qubit and 1 bit.
