  We re-visit Unclonable Encryption as introduced by Gottesman in 2003. We look
at the combination of Unclonable Encryption and Key Recycling, while aiming for
low communication complexity and high rate. We introduce a qubit-based
prepare-and-measure Unclonable Encryption scheme with re-usable keys. Our
scheme consists of a single transmission by Alice and a single classical
feedback bit from Bob. The transmission from Alice to Bob consists entirely of
qubits. The rate, defined as the message length divided by the number of
qubits, is higher than what can be achieved using Gottesman's scheme. We
provide a security proof based on the diamond norm distance, taking noise into
account.
