One is an LFSR functioning as a pseudorandom number generator. As such, it generates values uniformly distributed over a specific range in accordance with the LFSR size (M).

For that you’ll need a true random number generator (RNG), and this open-source hardware RNG uses one of the better methods we’ve seen.

A new random number generator that uses a micro laser developed by researchers at NTU Singapore is a hundred times faster than computer-based systems.

A new laser’s chaotic light beam lets the device generate multiple number sequences at once, similar to throwing multiple dice at a time.

While the outcome is always random when measuring a single particle, a pair’s properties are more correlated than classical physics dictates.
