Amazon researcher Mario Berta pcombined Rigetti's and IonQ's quantum processors to generate random numbers that can serve as the basis of cryptography keys.


Amazon Web Services' Mario Berta combined the capabilities of two quantum computers in order to generate truly random numbers to strengthen cryptographic keys.

Berta merged quantum processors from Rigetti and IonQ to exploit quantum particles' state of superposition, and the phenomenon that an equal number of quantum bits can yield a string of bits with an equal number of random values.

The processors generate two independent bit strings that are processed by a randomness extractor (RE) algorithm to combine multiple weakly random bit sources into one nearly perfect random string.
