Analysis for the Presence of Quantum Noise on the Teleportation

Quantum teleportation has provided us with an interesting way to transmit an arbitrary quantum state using one maximal entangled state and two classical bits of information. A variety of theoretical suggestions and experimental efforts have been made in this realm. In practical implementations of the teleportation protocol, quantum noise is an unavoidable factor. In this paper, we investigate the probabilistic quantum teleportation of two-particle. The fidelity of quantum state is calculated in detail, after suffering from the quantum noise. The relationship between quantum noise, quantum channel and quantum state fidelity is obtained. The effect of noise on the teleportation is analyzed.
