Researchers in Switzerland claim to have built a perfect random number generator from two quantum superconducting chips, a 30-meter-long pipe, and some software. The resulting device could be used to ...

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 ...

The orderly flow of information around the globe depends a lot on security, and at the heart of that security is randomness. Modern-day encryption relies on unpredictability to avoid being cracked, ...

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 ...

Andreas Wallraff and Renato Renner (f.l.t.r.) next to the 30-meter link connecting two quantum chips. Using this experiment, ETH researchers generated certified perfect randomness for the first time.

A physicist challenges the core idea of quantum mechanics, that events are truly random. He says a hidden framework of rules may influence outcomes. That’s because our current math makes quantum ...

Celebrate Pi Day and read all about how this number pops up across math and science on our special Pi Day page. Grab something circular, like a cup, measure the distance around the circle, and divide ...

Probability underpins AI, cryptography and statistics. However, as the philosopher Bertrand Russell said, “Probability is the most important concept in modern science, especially as nobody has the ...
