+#In this example, we produce fresh coin/random number with using quantum logical gates. While creating quantum random generator, steps of coin analogy was used.For this 1) a new qubit was produced and this stpe similar to fishing coin 2) applied hadamard gate, this step can be equal that tossing a  coin in air 3)Finally measured qubit and this is like that we can learn now the coin's result like head or tail
