PURE randomness is surprisingly difficult to create, even if you draw on the inherent randomness of quantum mechanics. Now, though, a “true” random number generator is on the cards, which may help create the ultimate cryptographic messages.
Existing quantum random number generators are only as reliable as their parts. For example, some devices send single photons through a and record the path taken, but a pattern could emerge over time if the beam-splitter comes to favour one direction or the materials degrade. A new number generator produces random strings of numbers without the worry of such flaws,…
