In this paper an area and power efficient 56T 4-bit comparator design has been presented by using GDI technique. The proposed 4-bit comparator design consist of 28 NMOS and 28 PMOS. A GDI full adder ...

Aiming to design a complete Quantum Information Processor (QIP), in this work, we are showing an efficient implementation of fault tolerant quantum comparator circuit. To ensure this fault tolerant ...
