              qc.h(0)
              qc.cx(0, 1)
              qc.measure([0, 1], [0, 1])
  
              # Use Aer's qasm_simulator
              simulator = Aer.get_backend('qasm_simulator')
  
              # Execute the circuit on the qasm simulator
              job = execute(qc, simulator, shots=1024)
  
              # Grab results from the job
              result = job.result()
  
              # Returns counts
              counts = result.get_counts(qc)
              print("nTotal counts are:", counts)
  
              # Draw the circuit
              print(qc.draw())
