Abstract:A scheme for probabilistically teleporting an unknown one-particle state of S-level by a group of pairs ofpartially entangled 2-level particle state is proposed. In this scheme unitary transformation and local measurement takethe place of Bell state measurement, then proper unitary transformation and the measurement on an auxiliary qubitwith the aid of classical communication are performed. In this way the unknown one-particle state of S-level can betransferred onto a group of remote 2-level particles with certain probability. Furthermore, the receiver can recover theinitial signalstate on an S-level particle at his hand.
Keywords:probabilistic teleportation   discrete Fourier transform   local measurement   one-particle state of S-level
