Excerpt on Majority Gate:
All three inputs get a vote, majority rules.


Excerpt on OR Gate:
Anchor (fix) one input at 1. Then if either of two free inputs goes to 1, get 1 as output.


Excerpt on AND Gate:
Anchor (fix) one input at 0. Then both of the free inputs must go to 1 in order to get 1 as output.


QCA's combined to form a binary adder (building block that allows computers to do math)
