Abstract

We propose a scheme to probabilistically teleport anunknown arbitrary three-level two-particle state by using two partialentangled two-particle states of three-level as the quantum channel. Theclassical communication cost required in the ideal probabilisticteleportation process is also calculated. This scheme can be directlygeneralized to teleport an unknown and arbitrary three-level K-particlestate by using K partial entangled two-particle states of three-level asthe quantum channel.
