Introduction
Cyber security is an important issue today. As the number of devices connected to the Internet continues to grow and more and more personal and business information is stored online, cyber security has become a major concern for businesses, governments and citizens.
Related to this, the emergence of quantum computing, with its ability to solve problems previously thought impossible with conventional systems, poses a major challenge for today’s computer security. This article examines its fundamentals and how it relates to quantum computing, as well as the potential threats and solutions being considered to meet these new challenges.
Quantum Computing: Fundamentals
Before discussing the implications of quantum computing for cybersecurity, it is important to understand how it works physically. Quantum computing is a different approach to traditional computing because it works thanks to the principles of quantum mechanics. Quantum mechanics is the theory that explains the behavior of elementary particles and how they interact with each other. It is based on the principle of quantum superposition, which states that quantum particles (such as electrons and photons) can be in several states at the same time. Instead of using bits to represent information, quantum computers use qubits that can be in multiple states at the same time.
