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…

Encrypted Qubits can be Cloned
Koji Yamaguchi, Achim Kempf
We show that encrypted cloning of unknown quantum states is possible. Any number of encrypted clones of a qubit can be created through a unitary transformation, and each of the enc…
