Quantum computers are the present emergent technology which uses reversible logic gates for designing quantum circuits classical logic gates are for conventional digital circuits where as reversible logic gates are building blocks of quantum circuits. power consumption in digital circuits can be drastically reduced by using reversible logic. In conventional digital circuits, during logical operations some bits of information are lost due to significant amount of energy is dissipated. So, this loss of bits of information can be avoided by using reversible logic gates. Reversible logic gates used to maximize the speed and reduce the time delay. Reversible technology plays an important role in nano technology and less energy complementary metal oxide semiconductor (CMOS) technology. This paper presents some of the reversible logic gates, advanced reversible logic gates like PV, SAM, Multiplexer, JK flip flop. JK flip flop with simple reversible logic gates and advanced reversible logic gates is designed. The power, delay in JK flip flop with reversible logic gates is observed as 2.49Mw, 2.18nsec and the power, delay in JK flip flop with advanced reversible logic gates is observed as 2.019Mw, 1.59nsec .From these results it is observed that JK flip flop with advanced reversible logic gates consumes less power and faster than JK flip flop with simple reversible logic gates.
