Reversible logic plays a vital role at present time and it has different areas for its applications, namely low‐power CMOS, quantum computing, nanotechnology, cryptography, optical computing, DNA computing, digital signal processing (DSP), quantum‐dot cellular automata (QCA), digital communications, and computer graphics. It is not possible to realize quantum computing without implementation of reversible logic. The main purposes of designing reversible logic circuits are to decrease quantum cost, depth of the circuits, and the number of garbage outputs. This chapter explains the basic reversible logic gates for more complex system, which may have reversible circuits as a primitive component and can execute complicated operations using quantum computers. The reversible circuits form the basic building block of quantum computers, as all quantum operations are reversible. This chapter presents the information related to the primitive reversible gates and helps researchers in designing higher complex computing circuits using reversible gates.
