This is a low bandwidth technique where a dedicated quantum link is provided between two points, and quantum mechanical effects are used to ensure that information transfer is secure and private.
Why is Quantum Random Number Generation (QRNG) superior to traditional pseudorandom number generators (PRNGs) in cryptographic systems?
QRNG utilizes inherent quantum phenomena to generate true random numbers, providing genuine unpredictability and non-reproducibility, whereas PRNGs use algorithms, producing numbers that, while appearing random, are deterministic and potentially predictable.
