# Create a Quantum Circuit acting on the q register
 circuit = QuantumCircuit(2, 2)
 Add a H gate on qubit 0
 circuit.h(0)
 # Add a CX (CNOT) gate on control qubit 0 and target qubit 1
 circuit.cx(0, 1)
 # Map the quantum measurement to the classical bits
 circuit.measure([0,1], [0,1])
 #Execute Phase:
 #Use Aer's qasm_simulator
 simulator = Aer.get_backend('qasm_simulator')
 Execute the circuit on the qasm simulator
 job = execute(circuit, simulator, shots=1000)
 Grab results from the job
 result = job.result()
 Return counts
 counts = result.get_counts(circuit)
 print("\nTotal count for 00 and 11 are:",counts)
 #Analyze
 Draw the circuit
 circuit.draw()
