Logic Adder

got a little further this afternoon with working on my quantum adder implementation, but its not really progressing well, I can get a cheated version working, but I have no idea how the extract the answer from the superposition of states. Also I'll actually have to use the quantum Registers at some point which I'm not using yet...

Oh yeah this is me adding 2 8bit numbers together using logic gates with 3 inputs and 2 outputs...
