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

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 on the output alone. The difficulty lies ...

Two quantum chips linked through a 30-meter cooled tube enabled scientists to create certified perfectly random numbers.ETH Zurich Researchers at ETH Zurich have developed a method to generate what ...

Creating perfect randomness is surprisingly difficult. Even modern random number generators never generate completely ideal random numbers: small systematic errors can result in some numbers appearing ...

Even the most modern random number generators do not produce perfectly random numbers, which can be a problem for cryptographic applications. ETH Zurich researchers use entangled superconducting ...
