Influence of Non-Uniform Magnetic Field on Quantum Teleportation in Heisenberg XY Model

Funds:the National Natural Science Foundation of China (10374007;60472021)
  • Received Date:2006-12-22
  • By considering the intrinsic decoherence, the validity of quantum teleportation of a two-qubit 1D Heisenberg XY chain in a non-uniform external magnetic field is studied. The fidelity as the measurement of a possible quantum teleportation is calculated and the effects of the non-uniform magnetic field and the intrinsic decoherence are discussed. It is found that anti-parallel magnetic field is more favorable for teleportation and the fidelity is suppressed by the intrinsic decoherence.
