First gates
This exercise should introduce the use of some basic gates. The identity HXH = Z is one of the most used identities. You should implement the method indetityHXH, which gets one qubit as an argument. Duplicate this qubit and then apply the gates H, X, and H to one qubit and Z to the other. Return them as a tuple. You will see that the values are the same. You can play with the input qubit in the main method.
