Abstract Graphs have provided an expressive mathematical tool to model quantum-mechanical devices and systems. In particular, it has been recently discovered that graph theory can be used describe design quantum components, devices, setups systems, based on the two-dimensional lattice of parametric nonlinear optical crystals linear circuits, different standard photonic framework. Realizing such graph-theoretical hardware, however, remains extremely challenging experimentally using...
Quantum networks provide the framework for quantum communication, clock synchronization, distributed computing, and sensing. Implementing large-scale practical relies on development of scalable architecture integrated hardware that can coherently interconnect many remote nodes by sharing multidimensional entanglement through complex-medium channels.

Software-defined networking (SDN) has been considered as a breakthrough progress for the next-generation LAN/WAN technologies. It enables fine-grained flow control that can make networks more customizable and flexible. However, transition of traditional model to SDN architectures poses scalability issues due possible entry explosion in switches. Typically, entries are removed from tables three ways, either at request controller, via switch expiry mechanism, or optional eviction mechanism. No...

Server replication mechanism is widely used to improve the availability and real-time characteristic of distributed services in Content Delivery Networks (CDNs). When performing delay-sensitive and/or throughput-sensitive applications such as P2P live streaming, a replica selection middleware that provides dependability timeliness faces an important problem regarding prevention timing failures, which may occur either under normal conditions or when quality service degrades due failures...
