How to get measurement result on Qiskit

Question

I want to get measurement result from my circuit output, like '00', '01', '10', or '11' because want to process it further classically. Any suggestion? We can see the highest probability '01'. How I can extract the result?

Answer 1

You need to know your job id fist. You can get it from https://quantum-computing.ibm.com/jobs:

With the job id and the backend, you can enter that information to retrieve the job in Qiskit:

from qiskit import IBMQ
provider = IBMQ.load_account()
job = provider.get_backend(<backend_name>).retrieve_job(<job_id>)

With the job, you can access the count like this:

counts = job.result().get_counts()
print(counts)

{'000000': 8,
 '000001': 16,
 '010000': 2,
 '010001': 3,
 '010100': 6,
 '010101': 2,
 '010110': 3,
 ...
}
