Encrypted clones can leak: Classification of informative subsets in Quantum Encrypted Cloning
Gabriele Gianini, Omar Hasan, Corrado Mio +3
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-…
