I recently made a quantum circuit that uses 32 qubits and try to run it on IBM Q Experience qasm_simulator backend. But it always ends with ERROR_RUNNING_JOB.

When i retrieve the job and display the error, i only got

"The following experiments failed:\n" without any details.

How i can get more information about the error?

The following is my qiskit version information:

{'qiskit': None, 'qiskit-terra': '0.8.0', 'qiskit-ignis': '0.1.1', 'qiskit-aer': '0.2.0', 'qiskit-ibmq-provider': '0.2.2', 'qiskit-aqua': '0.5.2'}

According to @Bram suggestion i run

$ pip install qiskit
Building wheels for collected packages: qiskit, qiskit-ibmq-provider
  Building wheel for qiskit (setup.py) ... error
  Complete output from command /home/userName/anaconda3/envs/quantum/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-install-kavivdyx/qiskit/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/pip-wheel-eak_06_d --python-tag cp37:

From this output i notice that wheel was failed in build, does that cause any problems?

I then run

$conda list | grep qiskit
qiskit                    0.11.0                   pypi_0    pypi

qiskit-aqua               0.5.2                    pypi_0    pypi
qiskit-chemistry          0.5.0                    pypi_0    pypi
qiskit-ibmq-provider      0.3.0                    pypi_0    pypi
qiskit-ignis              0.1.1                    pypi_0    pypi
qiskit-terra              0.8.2                    pypi_0    pypi
enter preformatted text here

and run the following in IPython console

>>import qiskit
{'qiskit': '0.11.0',
 'qiskit-terra': '0.8.2',
 'qiskit-ignis': '0.1.1',
 'qiskit-aer': '0.2.3',
 'qiskit-ibmq-provider': '0.3.0',
 'qiskit-aqua': '0.5.2'}

i will send another job and wait for the result.

Edit: The same error , ERROR_RUNNING_JOB, still occur, appear after the above update.

  • $\begingroup$ Installation is fine, wheel failure is not an problem, Did you try another standard example? ERROR_RUNNING_JOB could also mean a wrong line in youre code. Also the credentials needs to be set. $\endgroup$

  • $\begingroup$ @Bram If you mean IBMQ credentials of course i set them. I tried a smaller circuit with 28 qubit and it works without errors. The 32 qubit circuit use another subcircuit that is tested and used in the 28 quibt circuit. $\endgroup$ Jul 22, 2019 at 4:34
  • $\begingroup$ Hi, can you provide some more information about the circuit you are running and the parameters you are using to submit it? $\endgroup$

1 Answer 1


You're qiskit information shows 'qiskit': None. This should be 0.11 or smaller. Furthermore qiskit-ibmq-provider : 0.2.2 should be 0.3 for the latest version.
