报告内容摘要：Coherent superposition of quantum states is a peculiar feature of quantum theory. By adopting a proper resource framework, coherence of quantum states can be quantified systematically. Many coherence measures have been proposed, amongst which, coherence of formation and relative entropy of coherence are two important ones, corresponding to coherence cost and distillable coherence, respectively. In the meantime, quantum randomness is considered to be potentially a critical resource for information processing, which stems from quantum coherence. Considering individual and coherent measurement of the correlated party, we show that the coherence of formation and the relative entropy of coherence measure the quantum randomness for these two situations, respectively. Furthermore, we calculate the gap between the two quantum randomness and find its relation to quantum correlation.
