Quantum computing is an emerging computing paradigm at the intersection of computer science, physics and mathematics. Unlike classical computers that use bits — either 0 or 1 — as their fundamental computational blocks, quantum computers use quantum bits, or “qubits.” These qubits, governed by the principles of quantum mechanics, can exist in a state of superposition, where they can be both 0 and 1 simultaneously. This quality gives quantum computers computational power far beyond the reach of any traditional computer and has underscored their appeal.

This TechRepublic Premium article, written by Franklin Okeke, looks at specific quantum computing applications across different industries, their benefits and challenges.

Cybersecurity

Quantum computing and cybersecurity (quantum cybersecurity) offer stronger and more effective ways to protect our sensitive data compared to current methods. Its use case is beneficial in areas like quantum machine learning and generating random numbers with enhanced security.

Quantum random number generation is imperative for cryptography. While classical methods include pseudo-random number generators and true random number generators, quantum random number generators are TRNG types that get data from quantum events. Unlike regular TRNGs, QRNGs offer more random numbers using the inherent randomness in quantum physics, which provides a more sophisticated level of security as the generated numbers cannot be predicted even in the post-quantum state.
