A Novel Design of Reversible Universal Shift Register

Reversible logic gates provide power optimization which can be used in low power CMOS design, optical computing, quantum computing and nanotechnology. This paper propose a new 4*4 reversible RR gate that works as a reversible 4:1 multiplexer and has a reduced quantum cost. A novel design of Reversible Universal shift register using RR gates with reduced delay and quantum cost is proposed.
