Innovation Quinary and n‐Value toward Fuzzy Logic QCA Cell Design

Abstract

Quantum Cellular automata (QCA) is a technology developed to replace complementary metal‐oxide‐semiconductor (CMOS) technology that faces increasing challenges due to the miniaturization of CMOS dimensions. The use of multi‐valued QCA is of interest because of its proximity to fuzzy logic, and lower power consumption. A two‐layer quinary system is proposed and the basic logic gates are examined and simulated to confirm the correct performance of the proposed cell. The proposed cell employs two layers because the presence of more than two particles per layer destabilizes the design of logic gates. The proposed Quinary QCA(QuQCA) cell can be implemented in one layer using input and output derives. Simple relationships are proposed to calculate the polarization values and the number and type of layers, so complex quantum computations can be avoided. The quantum power consumption and the proposed cell power consumption of the quinary system are calculated and compared. Finally, we present n‐valued cells without using quantum computation, and these cells are examined in terms of the number of particles, polarization value, and cell structure. The n‐level cell can be investigated more easily than other technologies due to its proximity to fuzzy logic and the design of the input, output, and fuzzy membership function.

QQCAsim: a new simulation tool for quaternary logic in QCA technology

“…The methods of making semiconductor devices less than 10nm can be used some method such as field emission scanning probe (FE-SP) [27], plasmonic lithography [28], electron beam lithography using polymethylmethacrylate (PMMA) resist [29], and extreme ultraviolet (EUV) interference lithography [30]. It is also mentioned in [8,31] that the QQCA cell can be implemented in one layer using input and output drives. The clock in QQCA is similar to the clock in binary QCA and has four zones: switch, hold, release, and relax, which are used to control and transfer information simultaneously.…”
