Abstract :
This paper reports on the dynamic behavior of power dissipation in a clocked QCA majority gate. A distributed clocking scheme is employed in the QCA array to form a "computation wave" which moves smoothly across the circuit. The quantum dynamical calculation is done with coherence vector formalism with dissipation incorporated so that we can see power flowing to the environment, and also to and from the clocking circuit
