For example, here is the QCA design for an ADDER circuit. This arithmetic building block adds two binary digits (A and B) along with a carry digit from a previous addition, and produces a binary sum and carry digit.

More complex arrangements of QCAs could produce revolutionary new generations of microprocessors at the heart of future computers.
