Certifiably random: Swiss researchers claim perfect random number source
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 generate cryptographic keys, or to offer a “public randomness service” for lotteries or blockchain applications, they say. They’re not the first to make the claim. Many sources of randomness are biased. For example, coins or dice tend to favor one s…
© ETH Zurich Perfect random numbers were created for the first time as a result of random amplification. ETH Zurich proves this by means of a quantum experiment.
Our daily life seems deterministic: if you drop a pen, it falls. But on the quantum level, this certainty collapses in favor of probabilistic chaos. For decades scientists have been asking themselves a fundamental question: can we domesticate this chaos to generate a perfect chance, totally unpredictable? Thanks to an experiment using quantum intrication, a [...]
Perfect Randomness Realized For the First Time
ETH Zurich researchers say they have generated certified "perfect randomness" for the first time by using a quantum Bell-test setup with two entangled superconducting chips connected by a 30-meter cooled link. "In the long term, this work could play a similar role in digital security as atomic clock...
