JPMorgan Says Quantum Experiment Generated Truly Random Numbers

JPMorgan Chase & Co. has generated and certified so-called truly random numbers using a quantum computer, in a world-first that the bank hopes will have applications for security and trading.

Researchers created the sequence using a quantum computer built by Honeywell’s Quantinuum, according to a paper published in the scientific journal Nature on Wednesday. JPMorgan researchers, alongside Argonne and Oak Ridge national laboratories and the University of Texas at Austin, then became the first to prove mathematically that they had produced “genuine randomness.”

Most so-called random number generators, which are important for encrypting sensitive data, aren’t actually random. They’re pre-determined ...
