Qwires are two dimensional lines of say copper atoms, or any conductor, provided its not 3-dimensional. Left and/or right, but not up, down or diagonal. Intuitively fine.
The input is always the same as the output because all it does is...well...nothing much. It allows the input to travel along the single layer or line of copper atoms. A two-dimensional wire.
The next component is at least mathematically intuitive. NOT gates simply invert the input, whatever it may have been. Accordingly, two NOT gates in series reverse the input 'twice'...so the output is the same as the initial input. Groovy.
Finally, Hadamard Gates I find the most difficult to understand. After spending hours doing sums, two Hadamard Gates in series perform precisely the same function as two NOT gates in series. The output is also identical to the original input.
Accordingly, Qwires; 2 x NOT gates in series; and 2 x Hadamard gates in series all give identical output to that which was the original input.
Questions:
1. How can I make a NOT gate?
2. How can I make a Hadamard Gate?
3. What possible benefit arises from using two Hadamard Gates in series over and above a QW and/or over and above two NOT gates in series?
