Quantum Computing for Cryptography
Soma Debnath, Avishake Adhikary · 2025
With the exponential growth of computer systems, technology has drastically increased in the past few years. We have seen enormous growth in Information Technology, or the IT industries, which also helped other industries to grow faster. This exponential growth in the IT industries has resulted in the innovation of modern technologies. One of these new innovations is known as Quantum Computing. Computers have existed for decades, and researchers have continued to use them in our daily lives. Previously computers used 0s and 1s to calculate something or even generate behaviors through advanced computing strategies like Machine Learning (ML) or Deep Learning (DL) through Neural Networks. The use of 0 and 1 computation is known as the binary computation where the computer understood nothing but these two numbers. The advancement of the computer industry has been mesmerizing and the only thing limiting the industry was the computation time in terms of complex problems which was only possible for the binary computing computers to calculate the complex problems in terms of exponential time of ones and zeros in multiple dimensions. In today's world, users are facing massive security breaches to exchange information through the internet, and the requirement of a more secure way to encrypt our daily data and information for exchange and storing. Thus, holding the hand of quantum computing technology, the beginning of quantum cryptography. Quantum Cryptography uses physics rather than mathematics to encrypt or decrypt information. The purpose of this literature survey is to investigate the current state of the art in quantum cryptography and the future market trends in security domain. This research aims to contribute to the survey of quantum cryptography and how quantum cryptography has progressed over the years.
