Why quantum random is truly random: When a qubit in state |+> = (|0>+|1>)/sqrt(2) is measured, the outcome is fundamentally indeterminate — not just unknown, but physically undefined until measurement. This is guaranteed by the Born rule and verified by Bell inequality violations: no local hidden variable theory can reproduce quantum statistics. Unlike Math.random() which uses a deterministic PRNG seeded by the clock, quantum randomness has no seed, no state, and no pattern — ever.
