- Abstract: While quantum computers have the potential to perform a wide range of practically important tasks beyond the capabilities of classical computers, realizing this potential remains a challenge. One application is the generation of remotely certifiably random bits, which are appealing for applications involving mutually untrusting parties. Recently, leveraging the classical hardness of random circuit sampling, 70 kbits of certifiably random bits, which are secure against a realistic adversary using best-known attacks, was generated using a remotely accessed untrusted trapped-ion quantum processor. We will discuss the experimental protocol, security analysis, conditions for success, and outlook. We also identify promising applications in areas including cryptography, differential privacy, and blockchain that may benefit from certified randomness, improving the security and fairness.
