A system architecture for achieving long-distance, high-fidelity teleportation and long-duration quantum storage is proposed. It uses polarizationentangled photons and trapped-atom quantum memories and is compatible with transmission over standard telecommunication fibre. An extension of this architecture permits long-distance transmission and storage of Greenberger– Horne–Zeilinger states.

In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting a combination of circular holes and a star structure in the inner core clad causes the dispersion coefficient profile to be broadened, and addition...

In order to reduce costs and make it easier to integrate disparate systems, networked and virtual organizations (NVOs) should adopt open technology standards throughout the entire organization—standard computing architectures, standard networks, and standard application interfaces. The Internet protocol (IP) technology has been foreseen as a basic networking infrastructure that supports communi...

ITU-T G.9904 standard, also known as PoweRline Intelligent Metering Evolution (PRIME), is a Power Line Communications standard for advanced metering, grid control and asset monitoring defined by the International Telecommunication Union (ITU). In this paper, an analysis about how different characteristics of the communication channel and types of noise might affect the system performance is car...

Non-repudiation is a security service that provides cryptographic evidence to support the settlement of disputes. In this paper, we introduce the state-of-the-art of multi-party non-repudiation protocols, and analyze the previous work where one originator is able to send the same message to many recipients. We propose a new multi-party non-repudiation protocol for sending different messages to ...

Data Envelopment Analysis (DEA) requires that the data for all inputs and outputs are known exactly. When some outputs and inputs are unknown decision variables, such as bounded and ordinal data, the DEA model becomes a nonlinear programming problem and is called imprecise DEA (IDEA). The nonlinear IDEA program can be converted into a linear program by an algorithm based upon scale transformati...

Distributed Feature Composition (DFC) is a new component-based architecture for telecommunication services. Its principles are similar to the well-known pipe-and-filter architecture, adapted for use in the telecommunication domain. We present an overview of this architecture and explain how it might be used as a basis for componentbased development of telecommunication software. We also describ...
