High-dimensional quantum state transfer in a noisy network environment |
Decoherence effects on the high-dimensional QST proposal in a coupled-spin chain with either d = 3 (solid lines), or d = 5 (dotted–dashed lines). The average fidelity as functions of (a) J 0 with g 0 = J and T = 0.05 T N, (b) T with g 0 = J and S = 1/2, and (c) g 0 with J 0 = 5000 J and S = 1/2. |
