The new architecture for quantum cellular automata is offered. A QCA cell includes two layers nc-Si, divided by a dielectric. Among themselves cells are connected by the bridge from a conductive material. The comparison is made between this and QCA, offered earlier by C. Lent's group. Keywords—quantum cellular automata (QCA), nc-Si, Si/SiO2 superlattices, parallel computing
