Quantum Teleportation Under Different Collective Noise Environment

摘要： We investigate that the average fidelity of the standard quantum teleportation communication protocol when the quantum channel is affected by different local collective noise environments frequently encountered in real quantum communication protocol. We show that the quantum teleportation efficiency can be enhanced when the noise is unavoidable by choose the fit Bell state as the quantum channel, especially we can get perfect quantum teleportation efficiency under the local collective Pauli σy noise environment. Our work can shed some light on the application of practical standard quantum teleportation communication protocol.
