Abstract

It is crucial to take a closer look at digital encryption and the ways in which it is used— and broken—in order to comprehend the risk and what can be done about it. With quantum cryptography, neither the transmitter nor the receiver of the message can be tricked into compromising the system’s security. It has gained more attention recently and has emerged as one of the most promising areas of cryptography for quicker, more efficient, and more secure communication. However, compared to what the finest quantum computers of today have achieved, breaking quantum computers in the future will require 100,000 times more processing power and a 100 times lower error rate.

While it seems like quantum computing (QCom) has the ability to dramatically change a number of industries, cybersecurity is one that is put in jeopardy by its arrival. It is possible that Qcom (QCom) will make conventional cryptography methods useless. We still don’t fully understand the harmful implications of cybersecurity. Unfortunately, Qcom can influence cybersecurity in a few specific areas. When beginning to plan for ...
