【摘要】：在纳米技术领域,量子元胞自动机(quantum dot-cellular automata,QCA)可作为传统互补金属氧化物半导体(complementary metal oxide semiconductor,CMOS)电路的替代方案,具有可观的发展前景。QCA设备密度高,运行速度快,且功耗极低。在QCA中,可逆逻辑有着广泛应用。研究者已开发多个基于QCA的可逆逻辑电路,但基于QCA的可逆二进制减法器研究却不多见。QCA低功耗和高电流密度的特点,使其可用于设计纳米尺度节能逻辑电路。然而,其对大量逻辑门的需求和不利的无用输出,可能限制基于QCA逻辑电路的功能。我们利用QCA设计并实现了一个DG门,实现了DG门的普遍特征。利用该DG门的QCA部分,可以获得新的可逆二进制减法器。相比现有可逆减法器,我们设计的减法器量子成本低,无用输出少。电路设计与模拟基于QCA Designer-2.0.3软件。
[Abstract]:In the field of nanotechnology, quantum cellular automata (quantum dot-cellular automata,QCA) can be used as a substitute for traditional complementary metal oxide semiconductor (complementary metal oxide semiconductor,CMOS) circuits. Reversible logic is widely used in QCA. Researchers have developed a number of reversible logic circuits based on QCA, but the reversible binary subtraction based on QCA is not widely used in the design of nanoscale energy-saving logic circuits because of its low power consumption and high current density. However, its demand for a large number of logic gates and unfavorable output may limit the functionality of QCA-based logic circuits. We design and implement a DG gate with QCA, and realize the universal characteristic of DG gate. Using the QCA part of the DG gate, a new reversible binary subtraction can be obtained. Compared with the existing reversible subtraction, the quantum cost and useless output of the subtractive are lower. Circuit design and simulation are based on QCA Designer-2.0.3 software.
