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

时钟量子点元胞自动机电路的功耗
本文研究了时钟型QCA多数门的功耗动态特性。在QCA阵列中采用分布式时钟方案,形成在电路中平滑移动的“计算波”。量子动力学计算是用相干矢量形式进行的,并考虑了耗散,这样我们就可以看到能量流向环境,也可以从时钟电路流入和流出
