Physicists used quantum bits to achieve perfect randomness for the first time ever. The results of their research could strengthen cryptography and other security systems.

(Busà Photography/Moment/Getty Images) One of the hardest things to do in physics is to generate true, provably unpredictable randomness. That's because it's impossible to determine randomness based ...

Randomness forms a crucial backbone of modern society, where every encryption key, secure transaction and digital signature ...

Encryption systems rely on “random” numbers, but conventional computers can’t generate them perfectly. New research shows that quantum physics can.

Even the most sophisticated classical random number generators have minute biases that make their sequences predictable over ...

Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also ...

Breakthrough experiment uses quantum entanglement to generate mathematically provable random numbers for encryption and ...

If you want to pick a winner in a drawing, take samples for statistical purposes, or any of hundreds of other technical tasks you are going to need a source of random numbers. If you have ever looked ...
