High-dimensional quantum state transfer in a noisy network environment |
Variations of average fidelity 〈 F 〉 with quantum spin number for either d = 3 (solid lines), d = 4 (dashed lines), or d = 5 (dotted–dashed lines). (a) Coupled-spin cube; (b) coupled-spin chain of length N = 8. Here, the evolution time is the optimal time for the two different configurations. |
