We investigate quantum teleportation through dissipative channels andcalculate teleportation fidelity as a function of damping rates. It is foundthat the average fidelity of teleportation and the range of states to beteleported depend on the type and rate of the damping in the channel. Using thefully entangled fraction, we derive two bounds on the damping rates of thechannels: one is to beat the classical limit and the second is to guarantee thenon-existence of any other copy with better fidelity. Effect of the initiallydistributed maximally entangled state on the process is presented; and theconcurrence and the fully entangled fraction of the shared states arediscussed. We intend to show that prior information on the dissipative channeland the range of qubit states to be teleported is helpful for the evaluation ofthe success of teleportation, where success is defined as surpassing thefidelity limit imposed by the fidelity of 1-to-2 optimal cloning machine forthe specific range of qubits.
