Is global asymptotic cloning state estimation?
Yuxiang Yang, Giulio Chiribella
We pose the question whether the asymptotic equivalence between quantum cloning and quantum state estimation, valid at single-copy level, still holds when all the copies are examin…

Quantum replication at the Heisenberg limit
Giulio Chiribella, Yuxiang Yang, Andrew Chi-Chih Yao
No process in nature can perfectly clone an arbitrary quantum state. But is it possible to engineer processes that replicate quantum information with vanishingly small error? Here…

Confusability graphs for symmetric sets of quantum states
Giulio Chiribella, Yuxiang Yang
For a set of quantum states generated by the action of a group, we consider the graph obtained by considering two group elements adjacent whenever the corresponding states are non-…
