Locking up super-secret information with digital encryption has become even more secure with the production of numbers that aren’t just ‘nearly random’, but are truly unpredictable in every sense of the word.
Using the data generated by a three-year-old experiment on quantum entanglement, the US National Institute of Standards and Technology (NIST) recently generated codes that are guaranteed to be one of a kind, and it could set a new landmark in communications.
On one level, randomness is an easy thing to grasp. We flip coins, roll dice, and pick cards with a basic sense that the outcome can’t be easily predicted.
