Effects of inhomogeneous magnetic field on entanglement and teleportation in a two-qubit HeisenbergXXZchain with intrinsic decoherence
Jin‐Liang Guo, He‐Shan Song · Physica Scripta · 2008
We studied the effects of inhomogeneous magnetic field on entanglement and teleportation in a two-qubit Heisenberg XXZ chain with intrinsic decoherence taken into account. The dependences of the entanglement and fully entangled fraction on the inhomogeneous magnetic fields b and time t are investigated in detail. The contrast between different initial states, including pure and mixed states, is presented.
