Universal super-replication of unitary gates
G. Chiribella, Y. Yang, C. Huang
Quantum states obey an asymptotic no-cloning theorem, stating that no deterministic machine can reliably replicate generic sequences of identically prepared pure states. In stark c…

Superactivation of quantum gyroscopes
Giulio Chiribella, Rui Chao, Yuxiang Yang
Quantum particles with spin are the most elementary gyroscopes existing in nature. Can two such gyroscopes help two distant observers find out their relative orientation in space?…

Optimal asymptotic cloning machines
G. Chiribella, Y. Yang
We pose the question whether the asymptotic equivalence between quantum cloning and quantum state estimation, valid at the single-clone level, still holds when all clones are exami…
