Finite Block Length Analysis on Quantum Coherence Distillation and Incoherent Randomness Extraction
Finite Block Length Analysis on Quantum Coherence Distillation and Incoherent Randomness Extraction
We give the first systematic study on the second order asymptotics of the operational task of coherence distillation with and without assistance. In the unassisted setting, we introduce a variant of randomness extraction framework where free incoherent operations are allowed before the incoherent measurement and the randomness extractors. We then …
