Quantum Technology for Comparator Circuit

Quantum computing is the fusion of quantum physics and theoretical computer science that makes it more special and super faster than other traditional silicon-based computing systems. In this work, we have designed quantum 2-bit string comparator using the basic quantum AND, OR, NOT, XOR operations that are based on basic quantum CNOT, V, V+ gate operations. The proposed quantum comparator take the advantages of basic quantum computing to perform parallel processing and super-fast calculations.
