- Additional information
- The paper reports a collaboration between computer scientists and laboratory physicists, and describes the design, implementation, and rigorous security proof for a quantum random number generator. The security proof is comprehensive, assumes finite data, and is fully composable, i.e., the random numbers remain secure when generated as a subroutine in a larger cryptographic protocol. The design is unique in allowing that the photonic source is untrusted, yet nonetheless generating random bits at 8Gb/s – the fastest rate reported to date with composable security. The work was presented at QTech’20, and was highlighted in a popular article in Physics World: https://tinyurl.com/y3wsa8x7.
