Fidelity Of Teleportation Under Imperfect Measurements Through An Isotropic Channel

We design a noisy quantum teleportation protocol (NTP) in which noise factors are corresponded to noisy channels, imperfect measurement and non-maximally entangled channel (isotropic channel). The average fidelity of the quantum state transferred in a standard quantum teleportation protocol (STP) with introduced noise is obtained in this work. Then we fine the average fidelity for NTP. We show that the average fidelity depends on the variations of noise factors and their effects on each other involved in STP and NTP.
