Quantum-dot Cellular Automata (QCA) presents a new model at Nano-scale for possible substitution of conventional Complementary Metal–Oxide–Semiconductor (CMOS) technology. On the other hand, an Arithmetic Logic Unit (ALU) is a digital electronic circuit which performs arithmetic and bitwise logical operations on integer binary numbers. Therefore, QCA-based ALU is an important part of the processor in order to develop a full capability processor. Although the QCA has become very important, there is not any comprehensive and systematic work on studying and analyzing its important techniques in the field of ALU design. This paper provides the comprehensive, systematic and detailed study and survey of the state-of-the-art techniques and mechanisms in the field of QCA-based ALU designing. There are three categories in which QCA plays a role: ALU, logic unit (LU) and arithmetic unit (AU). Each category presents the important studies. In addition, this paper reviews the major developments in these three categories and it plans the new challenges. Furthermore, it provides the identification of open issues and guidelines for future research. Also, a Systematic Literature Review (SLR) on QCA-based ALU, LU and AU is discussed in this paper. We identified 1,960 papers, which are reduced to 26 primary studies through our paper selection process. According to the obtained results from 2001 to 2015, the number of published articles are very high in 2014 and low in 2005 and 2009. This survey paper also provides a discussion of considered mechanisms in terms of ALU, LU and AU attribute as well as directions for future research.
