Affordable and sustainable? Not anymore.

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 ...

Eeny, meeny, miny, mo, catch a tiger by the toe – so the rhyme goes. But even children know that counting-out rhymes like this are no help at making a truly random choice. Perhaps you remember when ...

Randomness is essential today. From encrypting sensitive information to simulating biological systems, unpredictable numbers are indispensable. Yet most everyday random numbers aren’t truly random.

Games have used chance since the first roll of dice. Whether someone spins a colorful slot reel or opens a loot box, the next outcome is always unknown. From board games to modern phone apps, chance ...
