Design of Single-Bit Fault-Tolerant Reversible Circuits

Abstract

This article introduces redundant design approaches for reversible circuits (RCs) that have the ability to detect and tolerate single-bit fault without the need of conventional voting scheme. Experiments preformed show that the proposed scheme reduces the gate cost on average with up to 28% as compared with tri-modular redundant circuits. RCs have direct relation with quantum computation which are largely to loss of energy levels due to the phenomenon of quantum decoherence that cause single point failures.
