How can the application of quantum computing revolutionize the field of cryptography, and what potential implications does this hold for ensuring data security in the future?
Quantum computing would make it faster to compute complex problems like factorization and logarithms which are used in encryption. Quantum computing uses qubits which are made of a quantum system like a proton or electron so it exhibits their properties and they are way different from the binary bits that classical computers use. Qubits hold properties of superposition, entanglement and inference and these properties are being exploited to enable faster computation.
Asymmetric algorithms like RSA use factorization to encrypt data. Therefore, with the development of quantum computing the currently existing cryptography won’t be safe anymore. But quantum computing would also make it easier to develop stronger algorithms to encrypt data. It allows quantum machine learning which helps with finding anomalies, classifying data and also predicting patterns. Random generation of numbers by quantum computing which is a major and integral part of cryptography can also help in developing quantum cybersecurity solutions.
