I have code which runs on the IBMQ website perfectly, however copying and pasting the same code (and including my API token) the same code does not run when I try and run it on a real quantum computer from Jupyter notebook. My code is :
import math
import certifi
import matplotlib.pyplot as plt
import numpy as np
from math import pi
from qiskit import QuantumCircuit, ClassicalRegister, QuantumRegister, execute, Aer,BasicAer, IBMQ
from qiskit.compiler import transpile, assemble
from qiskit.tools.jupyter import *
from qiskit.visualization import *
from qiskit.tools.visualization import circuit_drawer
from qiskit.quantum_info import state_fidelity
backend = BasicAer.get_backend('unitary_simulator')
IBMQ.save_account('My_token', overwrite=True)
IBMQ.load_account()
provider = IBMQ.get_provider(hub='ibm-q-research')
#circuit I want to run
def circtest(x1,x2,shotsin):
maxShot=shotsin
import random
zz=[x1,x2]
qr=QuantumRegister(1)
my_layout={qr[0]:4}
circuit2 = QuantumCircuit();
circuit2.add_register(qr)
cr=ClassicalRegister(1)
circuit2.add_register(cr)
circuit2.initialize(zz,0)
circuit2.measure(0,0);
device = provider.get_backend('ibmq_casablanca')
Cfin=circuit2;
result = execute(circuit2,backend=device,shots=maxShot).result()
counts = result.get_counts(0)
return counts
However running the simple test
#simple test
circtest(1,0,100)
returns the following error:
---------------------------------------------------------------------------

I assume I am just missing some way in which I can communicate with the actual devices but I am not sure what this is
