Overview

• In its first 40 days of operation, CURBy produced random numbers on 7,434 of 7,454 attempts, translating to a 99.7% success rate.
• The beacon derives its output from Bell-test measurements of entangled photon pairs transmitted between separate labs in NIST’s Boulder complex.
• Researchers implemented the Twine protocol, a quantum-compatible blockchain system that hashes and timestamps each data set for transparent auditing and tamper detection.
• As a public service, CURBy is among the first to offer quantum-generated randomness with a provable advantage over classical pseudorandom generators.
• Anyone can access the daily random numbers online for uses such as lotteries, jury selection, clinical trials or security applications requiring high-quality randomness.
