Query: Coherence as a resource for source-independent quantum random-number
  generation   Measuring quantum states provides means to generate genuine random numbers.
It has been shown that genuine randomness can be obtained even with an
uncharacterized quantum source. In this work, we propose a framework that
formalizes the idea of realizing source-independent quantum random number
generation via measuring coherence. Without full state tomography, the
coherence of the source can be estimated by coherence witnesses. The existing
uncertainty-relation-based schemes can be treated as special cases under the
coherence framework, as we design a nonlinear coherence witness that can
essentially yield the same results. Meanwhile, we propose a source-independent
random number generation scheme, which can achieve a higher randomness
generation rate than the uncertainty-relation-based ones.
