I am looking for a source of sequence of quantum random numbers, in fact bit sequences of 0 and 1. I had been using the quantumrandom API but since it is no longer working properly (another question) I was looking for an alternative and I found qrng.
qrng say that is using the quantum computers of IBM Qiskit to generate random numbers. I have an account and set the backend to one of the quantum computers that are available in the dashboard ('ibmq_quito'), and run the following lines to generate a sequence of 1024 bits b:
from qiskit import IBMQ
import qrng
provider = IBMQ.load_account()
qrng.set_backend('ibmq_quito')
b=qrng.get_bit_string(int(1024))
The problem is I cannot verify that I am actually downloading numbers and not using a pseudorandom simulator process. My suspicions are mainly for two reasons:
If I change the backend to a random string e.g. ibmq_stackoverflow it will still work with no difference
The whole process is happening very fast when I use an iteration
I would appreciate any help on that, Thanks a lot
