Why is Quantum Random Number Generation (QRNG) superior to traditional pseudorandom number generators (PRNGs) in cryptographic systems?

Quantum Random Number Generation (QRNG) taps into the intrinsic randomness of quantum phenomena, such as a radioactive atom’s decay or a photon’s polarization, to generate numbers that are fundamentally random and thus unpredictable. This true randomness is pivotal in cryptographic systems, ensuring the generation of secure keys that are not susceptible to prediction or reproduction. In contrast, pseudorandom number generators (PRNGs) utilize algorithms to produce number sequences that, while seeming random, are deterministic and can be reproduced if the initial seed value is known. This deterministic nature could potentially be exploited, making QRNG a more secure and reliable choice for cryptographic applications, especially in generating encryption keys that demand utmost unpredictability.
