Certified Randomness Uses Quantum Cryptography to Make Stronger Keys

**Executive summary:** Researchers and companies demonstrated and plan to commercialize "certified randomness," using quantum Random Circuit Sampling on a 56-qubit trapped-ion device to generate mathematically verifiable random bits intended to strengthen cryptographic key generation for protocols like RSA, AES, and TLS; the approach promises higher-quality randomness and new use cases (e.g., lotteries, proof-of-stake), but faces practical verification costs and hardware implementation challenges before broad deployment.
