While the outcome is always random when measuring a single particle, a pair’s properties are more correlated than classical physics dictates.
For example, traditional computers may create encryption based on the result of multiplying two large prime numbers together, generating a seemingly random number.
Quantum mechanics used to generate truly random numbers for encryption, incorporating blockchain for traceability and security.
The main source of randomness — entropy, if you will — is a pair of transistors hooked up to create a bunch of avalanche noise that is apparently truly random, much like the zener diode method.
Digital random number generation is more common today, with complex algorithms producing pseudo-random outcomes based on complex mathematical equations.
