qiskit.qasm3.dumps raise TypeError: only length-1 arrays can be converted to Python scalars #13362
Description
Environment
- Qiskit version:
qiskit 1.2.4
qiskit-aer 0.15.0
qiskit-aer-gpu 0.14.2
qiskit-algorithms 0.3.0
qiskit-ibm-provider 0.11.0
qiskit-ibm-runtime 0.30.0
qiskit-qasm3-import 0.5.0
- Python version:
Python 3.12.2 | packaged by conda-forge | (main, Feb 16 2024, 20:50:58) [GCC 12.3.0] on linux
- Operating system:
Ubuntu 24.04.1 LTS x86_64
What is happening?
A numpy type error raised during the execution of qiskit.qasm3.dumps .
How can we reproduce the issue?
from qiskit import QuantumCircuit
from qiskit.quantum_info import random_unitary
from qiskit.qasm3 import dumps
qc = QuantumCircuit(4)
for i in range(4):
qc.h(i)
qc.append(random_unitary(2),[i])
print(qc.draw())
dumps(qc)or
from qiskit import QuantumCircuit
from qiskit.quantum_info import random_unitary
from qiskit.qasm3 import dumps
qc = QuantumCircuit(4)
for i in range(4):
qc.h(i)
qc.append(random_unitary(2).to_instruction(),[i])
print(qc.draw())
dumps(qc)What should happen?
I should be able to dump this circuit to QASM3 because qiskit.qasm2.dumps can successfully dump this circuit.
Any suggestions?
