Randomness is critical for many information processing applications, including numerical modeling and cryptography. Reliance on imperfect random numbers has been the Achille’s heel in many cyber-attacks. We tackle this problem with the Entropy protocol on our MosaiQ, our quantum processor. This unique combination generates certifiably-random numbers. Mosaiq provides a quantum advantage, essential in data encryption, on a small-scale photonic device.


Quandela’s contributions are both theoretical and experimental. Our protocol measures the amount of information that an eavesdropper could potentially use to fake violation of locality, and then sets a bound on how well the device should perform if it is to still produce certified random numbers. The device also periodically tests itself to validate these numbers. It is now provided experimentally validated on MosaiQ.
