Multiple-shot labeling of quantum observables
Seyed Arash Ghoreishi, Nidhin Sudarsanan Ragini, Sk Sazim +1
Quantum labeling tasks ask one to recover the missing associations between classical outcome labels and the effects forming the POVM. We study labeling in the multiple-shot regime,…

Semi-device-independent channel identification with communication matrices
Samgeeth Puliyil, Leevi Leppäjärvi, Mário Ziman
We look into the task of differentiating between any two quantum channels and reconstructing them from the obtained measurement statistics with possibly limited information about t…

Single-shot labeling of quantum observables
Nidhin Sudarsanan Ragini, Mário Ziman
We identify and study a particular class of distinguishability problems for quantum observables (POVMs), in which observables with permuted effects are involved, which we call as t…
