Experimental demonstration that qubits can be cloned at will, if encrypted with a single-use decryption key
Koji Yamaguchi, Leon Rullkötter, Ibrahim Shehzad +3
The no-cloning theorem forbids the creation of identical copies of qubits, thereby imposing strong limitations on quantum technologies. A recently-proposed protocol, encrypted clon…
