e-Star: Telescopes and Databases as a Single Information Grid
We present a sketch of a system which consists of a Grid of databases and telescopes within which intelligent agents assess the information available... -
Inter-Operability of ESA Science Archives
ESA Science Archives for ISO and XMM-Newton have been developed by the Science Operations and Data Systems Division in Villafranca, Spain. By using... -
The Prototype TNG Long-Term Archive and its Interactions with the Italian GRID Project
A pilot project is currently being carried out, aiming at demonstrating the feasibility of technical solutions for the construction of the Long-Term... -
Data Mining Facility
A major goal of the Virtual Observatory is to build tools for exploring and extracting new information from heterogeneous (and possibly very large)... -
The UDAPAC Project - Uccle Direct Astronomical Plate Archive Centre: A New International Facility for Inherited Observations
We discuss a project to create a centralized astronomical direct-plate archive and digitizing facility, with a view to making photographic data fully... -
Aladin in the VO Context
Aladin, the CDS interactive sky atlas is one of the important interoperability tools of the astronomy Web. Several recent improvements prepare it for... -

3 Maximum-Likelihood Methodsin Quantum Mechanics
Maximum Likelihood estimation is a versatile tool covering wide range of applications, but its benefits are apparent particularly in the quantum... -
6 Quantum Tomography from Incomplete Data via MaxEnt Principle
We show how the maximum entropy (MaxEnt) principle can be efficiently used for a reconstruction of states of quantum systems from incomplete... -
11 Discrimination of Quantum States
The problem of discriminating among given nonorthogonal quantum states is underlying many of the schemes that have been suggested for quantum... -
7 Experimental Quantum State Tomography of Optical Fields and Ultrafast Statistical Sampling
We review experimental work on the measurement of the quantum state of optical fields, and the relevant theoretical background. The basic technique... -
12 Quantum States: Discrimination and Classical Information Transmission.A Review of Experimental Progress
The purpose of this chapter is to review the experimental achievements made to date in two closely related areas of quantum information science.... -
Scalable Metadata Definition Frameworks
The VO will be an evolving environment that will enable increasingly complex interactions between resources. Naturally, expanding capabilities will...
