Programmable reversible logic is emerging as a prospective logic design style for implementation in modern nanotechnology and quantum computing with minimal impact on circuit heat generation. Recent advances in reversible logic using and quantum computer algorithms allow for improved computer architecture and arithmetic logic unit designs. In this paper, the two novel 4×4 reversible logic gates (MRG and PAOG) are used with minimal delay, and may be configured to produce a variety of logical calculations on fixed output lines based on programmable select input lines.
