Abstract

Quantum random number generation (QRNG) is an important cryptographic primitive. Various security models exist from the fully trusted to the fully device independent scenario. Here we look at the middle-ground of semi source independence (where the only thing known about the source is the dimension) and where measurements are not ideal (e.g., there may be loss and detector inefficiencies). We show how to compute optimistic bit generation rates even in this strong security model and our methods may be broadly applicable to other quantum cryptographic protocols in this setting.
