The document summarizes a method for generating verifiably random numbers using the principles of quantum entanglement and Bell's theorem. It involves measuring the spin properties of entangled electron pairs from different angles and showing their results violate Bell's inequality, proving the results are genuinely random. The technique could be used to produce cryptographically secure random numbers for applications like key generation, with some practical challenges around maintaining entanglement and preventing signaling between the measurement devices.

2. Why? Pseudo random numbers may have patterns known to attackers. There is need for a source of randomness that can be verified to be genuinely random.
