How to run a simulated circuit: https://quantum-computing.ibm.com/lab/docs/iql/first-circuit#execute-the-experiment

• first run simulation:

•   simulator = Aer.get_backend('qasm_simulator')
    result = execute(circuit, backend = simulator).result()
    from qiskit.tools.visualisation import plot_histogram
  

• Running on IBM quantum:

•   IBMQ.load_account() 
    provider = ibm.get_provider('ibm-q')
    qcomp = provider.get_backend('ibmq_16melbourne')
    job = execute(circuit, backend = qcomp)
    from qiskit.tools.monitor import job_monitor
    result = job.result 
    plot_histogram(result.get_count)
  

  NEED to get an API token!

    from qiskit import IBMQ
    IBMQ.save_account('insert token here')
    ibm.load_account()
