This paper proposes a new cell configuration for quaternary Quantum Cellular Automata (QQCA) based on the calculation of polarization. The proposed QQCA cell is based on a three-particle system that creates instability within a cell in the gate design. Therefore, a single-particle system or binary QCA (bQCA) technology and a two-particle system or Ternary QCA (TQCA) technology have been used to implement quaternary logic. The proposed cell can be implemented in two layers or in one, using input and output drives. According to the dimensions of the proposed model for QQCA and simulation of basic gates, designing with this cell is quite optimal; it requires five cells in the design of the AND and OR gates and two cells in the design of the NOT gate. Based on the number of cells used in the basic gates, the total area in the AND and OR gates is 576 × 10⁻⁶ µm² and in the NOT gate is 276 × 10⁻⁶ µm². The base gates are fully optimized and latency is equal to 0.25 clockcycle or 0.25 × 10⁻¹²s, which is reduced in comparison with prior works. Also, the power consumption of a cell in terms of quantum calculation and the proposed model is also investigated.

创新 QCA 四元逻辑门的设计与仿真

本文提出了一种基于极化计算的四元量子元胞自动机 (QQCA) 的新单元配置。提出的 QQCA 单元基于三粒子系统，该系统在栅极设计中的单元内产生不稳定性。因此，已经使用单粒子系统或二元QCA（bQCA）技术和双粒子系统或三元QCA（TQCA）技术来实现四元逻辑。所提出的单元可以使用输入和输出驱动器在两层或一层中实现。根据提出的 QQCA 模型的尺寸和基本门的模拟，使用该单元进行设计是非常理想的；它在与门和或门的设计中需要五个单元，在非门的设计中需要两个单元。根据基本门中使用的细胞数量，^-6 µm ²并且在非门中为276 × 10 ^-6 µm ²。基本门完全优化，延迟等于 0.25 个时钟周期或 0.25 × 10 ^-12 s，与之前的工作相比有所减少。此外，还研究了在量子计算方面的单元功耗和所提出的模型。
