Average subentropy, coherence and entanglement of random mixed quantum states
Lin Zhang, Uttam Singh, Arun Kumar Pati
Compact expressions for the average subentropy and coherence are obtained for random mixed states that are generated via various probability measures. Surprisingly, our results sho…

Cohering power of quantum operations
Kaifeng Bu, Asutosh Kumar, Lin Zhang +1
Quantum coherence is a basic feature of quantum physics. Combined with tensor product structure of state space, it gives rise to the novel concepts such as entanglement and quantum…

Average coherence and its typicality for random pure states
Uttam Singh, Lin Zhang, Arun Kumar Pati
We investigate the generic aspects of quantum coherence guided by the concentration of measure phenomenon. We find the average relative entropy of coherence of pure quantum states…
