Basic Reversible Logic Gates and It's Qca Implementation

Reversible logic has various applications in various field like in Nanotechnology, quantum computing, Low power CMOS, Optical computing and DNA computing, etc. Quantum computation is One of the most important applications of the reversible logic.Basically reversible circuits do not lose information & reversible computation is performed only when system comprises of reversible gates. The reversible logic is design,main purposes are - decrease quantum cost, depth of the circuits & the number of garbage output. This paper provides the basic‘s of reversible logic gates & its implementation in qca.
