I can't load account on IBM's qiskit

Question

I do this but it still gives an error for load account

• IBMQ.delete_account()
• IBMQ.active_account()
• IBMQ.save_account('myAPI toke ')
• IBMQ.save_account('my API toke')
• IBMQ.load_account()

entire error

HTTPError Traceback (most recent call last) C:\111\lib\site-packages\qiskit\providers\ibmq\api\session.py in request(self, method, url, bare, **kwargs) 277 response = super().request(method, final_url, headers=headers, **kwargs) --> 278 response.raise_for_status() 279 except RequestException as ex:

The above exception was the direct cause of the following exception:

I perform this operation, but again it gives an error for load account

Answer 1

I suggest to install the latest version of qiskit and follow the documentation you can find here, about the class IBMProvider: https://github.com/Qiskit/qiskit-ibm-provider

Here is an example program:

# This code works with qiskit 0.41.0

# Import Qiskit
from qiskit import QuantumCircuit, ClassicalRegister, QuantumRegister, QiskitError
from qiskit import execute
from qiskit_ibm_provider import IBMProvider
from qiskit_ibm_provider import least_busy

try:

    # Create a Quantum Register with 2 qubits.
    q = QuantumRegister(2)
    # Create a Classical Register with 2 bits.
    c = ClassicalRegister(2)
    # Create a Quantum Circuit
    qc = QuantumCircuit(q, c)

    vector = [0.5, 0.5, 0.5, 0.5]

    qc.initialize(vector)
    qc.draw()
    # Add a Measure gate to see the state.
    qc.measure(q, c)

    # the following instruction must be used the very first time, then commented
    # IBMProvider.save_account(token='MY_API_TOKEN') 

    # the following instruction is the one you will use always
    provider = IBMProvider()

    # display current supported backends
    print(provider.backends(min_num_qubits=5, simulator=False, operational=True))

    small_devices = provider.backends(min_num_qubits=5, simulator=False, operational=True)
    backend = least_busy(small_devices)
    print(backend)

    #running the job
    job_exp = execute(qc, backend, shots=2048)
    result_exp = job_exp.result()

    # Show the results
    print('Counts: ', result_exp.get_counts(qc))


except QiskitError as ex:
    print('There was an error in the circuit!. Error = {}'.format(ex))
