Squaring in Reversible Logic Using Zero Garbage and Reduced Ancillary Inputs

In this paper, our objective is to design an efficient dedicated squaring architecture in reversible logic using reduced ancillary inputs and zero garbage outputs. The proposed design has a modular structure and has been built recursively. The quantum cost optimization has been achieved using NCV-|1 > and NCV-|v
₁
> and double gate libraries. The performance parameters like ancillary inputs, garbage outputs and quantum cost have been formulated from the design and compared with a very recent work [1].
