Adiabatic hamming code generator-checker using 4-dot-2-electron quantum dot cellular automata

Abstract

Technological advancements have witnessed rapid regression of Moore’s Law within the past few years. With rising demand for higher clocking speeds, CMOS has already started exhibiting threshold limitations. Reversible Logic has emerged as a suitable alternative with near zero heat dissipation attribute. Quantum Dot Cellular Automata (QCA) has adopted the concept of reversibility and emerged as a primitive tool for quantum architecture deigns with clocking near Terra-Hertz range. A plethora of quantum architectures based on QCA cells have been proposed till date. With rise of research on digital designs based on QCA, multiple literary proposals exist which realize digital designs incorporating QCA cells. This communication proposes a Hamming Code Generator-Checker architecture design using 4-dot-2-electron QCA cells. We employ an existing QCA based XOR gate literary proposal for designing the proposed architecture. Peer comparison with literary counterparts has proven our design to fare better with a gain of 60.6% in area.
