Quantum deletion is possible
Year: 2000
Type: preprint
Abstract: A deleting operation is introduced which differs from the commonly used {\\it controlled-not} (C-not) conditional logical operation $-$to flip the (classical or quantum) state of the last copy in a chain in a deletion process. It is completely reversible, in the classical case, possessing a most natural cloning operation counterpart. We call this deleting procedure R-deletion since, in a way, it can be viewed as a `randomization' of the standard C-not operator. It is a nonlinear operation and has the remarkable property of avoiding in a simple manner the `impossibility of deletion of a quantum state' principle, put forward by Pati and Braunstein recently \\cite{pbn1}.
