Not all random numbers are created equally. The method used to generate them has direct implications for security, predictability, and suitability across different applications. This article explains the key differences between quantum random number generators and pseudorandom number generators. What is a PRNG? A pseudorandom number generator is an algorithm that produces a sequence of…

A quantum random number generator produces random numbers by measuring the outcome of quantum physical processes. To understand why this produces genuine randomness, it helps to understand a key principle of quantum mechanics. The quantum principle behind QRNG In classical physics, if you know the state of a system precisely enough, you can predict its…

Randomness is everywhere in digital security. It underpins encryption keys, authentication tokens, secure communications protocols, and many other systems we rely on daily. But not all randomness is equal, and the source of that randomness matters more than most people realise. A quantum random number generator, or QRNG, is a device that produces random numbers…
