(Color online) (a) Proposed hybrid QKD network on large scales. Each switch or repeater can have many endpoint users and those attached to repeaters have high priority in terms of security. (b) Illustration of a small portion of a large-scale hybrid network. A component of the relay network can connect directly with another component or it can use controlled switches to activate a connected path when needed. Each repeater can have many switches attached, which can connect to more switches or directly to endpoint users. Well-protected, high-priority endpoint users can be connected directly to a repeater.

FIG. 2.

(Color online) For a small-world network of N = 1000 nodes, (a) in the parameter plane (N e , β), contour plot of the fraction N a /N of nodes affected by a perturbation to cause the node with the largest degree to overload, and (b) N a /N versus N e for fixed photon-generation rate β = 0.91. Each data point is the average of 1000 network realizations.

FIG. 3.

(Color online) (a) The contour plot of the fraction of affected node N a /N by perturbing the node with largest bandwidth versus the average degree for scale-free networks. Network size N = 1000. (b) A cross section indicated by the dashed line in (a). (c) The contour plot of the fraction of affected node N a /N versus the average number of inter-cluster links per cluster for clustered networks. N = 1000, the number of clusters is M = 10. Each cluster is a scale-free subnetwork with average degree 10. (d) A cross section indicated by the dashed line in (c). The photon generating rate β is 0.855 for scale-free networks (b) and 0.8 for clustered networks (d). Each data point is the average of 1000 ensembles.
