Beyond the Canonical Protocol: Quantum Encrypted Cloning from Secret-Sharing Access Structures
Gabriele Gianini, Stelvio Cimato, Jianyi Lin +3
Quantum encrypted cloning shows that an unknown quantum state can be distributed into multiple encrypted copies without contradicting the no-cloning theorem: each copy is unusable…

Full characterization of informative subsets in Quantum Encrypted Cloning
Gabriele Gianini, Stelvio Cimato, Jianyi Lin +2
Quantum encrypted cloning, introduced by Yamaguchi and Kempf, is a Pauli-based protocol that distributes an unknown input qubit into multiple encrypted signal-noise pairs in such a…

Encrypted clones can leak: Classification of informative subsets in Quantum Encrypted Cloning
Gabriele Gianini, Omar Hasan, Corrrado Mio +2
Encrypted cloning enables the redundant storage of an unknown qubit while remaining compatible with the no-cloning theorem, since only one clone can later be recovered through key-…
