Randomness, very important.*
From Observer, March 27:
A JPMorgan-backed experiment used quantum hardware to generate certified randomness—yes, really—which could one day power cryptography, simulations and whatever comes after the blockchain gold rush.
Pulling numbered balls out of a mixing machine. Tracking the twitch of a mouse cursor. Converting lava lamp motion into data. These are just a few ways real-world randomness is generated—essential for things like lotteries and Internet encryption, where unpredictability equals security.
Transmitting that randomness over the Internet, however, is a different story. Physically random processes are hard to verify remotely, and by design, traditional computers can’t generate true randomness. But a new quantum breakthrough may have solved the problem.
Published yesterday (May 26) in Nature, a study from JPMorgan Chase researchers—alongside collaborators at Argonne and Oak Ridge national labs and the University of Texas at Austin—demonstrates how a quantum computer generates “certified” randomness....
