In this paper we present two designs using the reversible $R^3$ gate to perform the quantum half adder/ subtractor and the quantum full adder/subtractor. The proposed half adder/subtractor design can be used to perform different logical operations, such as $AND$, $XOR$, $NAND$, $XNOR$,...
By using any full subtractor logic circuit, full subtractor using NAND gates and full subtractor using nor gates can be implemented, since both the NAND and NOR gates are treated as universal gates. Here is a question for you, what is the difference between half subtractor and full subtractor?

Full Adder using Two Half Adders Full Adder Design with using NAND Gates A NAND gate is one kind of universal gate, used to execute any kind of logic design. The FA circuit with the NAND gates diagram is shown below. FA using NAND Gates FA is an easy one-bit adder and if we desire...
A full-subtractor is a combinational logic circuit that performs subtraction using inputs of three binary digits: one minuend and two subtrahends, and considers eight input states: (0,0,0), (0,1,0), (1,0,0), (1,1,0), (0,0,1), (0,1,1), (1,0,1), and (1,1,1). ...

Over the past decade, DNA has demonstrated remarkable potential in fabrication of molecular logic and arithmetic systems. In this work, a simple DNA-based system mimicking a full-subtractor that handles three inputs including one minuend and two subtrahe
This study presents a technique for implementing all-optical Full Adder (FA) and Full Subtractor (FS) functionalities utilizing a Fiber Bragg Grating (FBG) structure. The proposed method exploits the cross-phase modulation (XPM) mechanism within a phase-shifted FBG (PSFBG)...
2.2. Conventional QCA Reversible Full Adder-Subtractors Recently, various reversible gates have been proposed, and efficient RFAS using them are being proposed. As shown in the truth table in Table 2, RFAS has three inputs, A, B, and C, and three outputs, Carry, Borrow, and Sum/Diff....
