Quantum information science is a new field of science and
technology which requires the collaboration of researchers coming
from different fields of physics, mathematics, and engineering:
both theoretical and applied. Quantum Computing and Quantum Bits in
Mesoscopic Systems addresses fundamental aspects of quantum
physics, enhancing the connection between the quantum behavior of
macroscopic systems and information theory. In addition to
theoretical quantum physics, the book comprehensively explores
practical implementation of quantum computing and information
processing devices. On the experimental side, this book reports on
recent and previous observations of quantum behavior in several
physical systems, coherently coupled Bose-Einstein condensates,
quantum dots, superconducting quantum interference devices, Cooper
pair boxes, and electron pumps in the context of the Josephson
effect. In these systems, the book discusses all required steps,
from fabrication through characterization to the final basic
implementation for quantum computing.

This volume is an outgrowth of the Second International Workshop on
Macroscopic Quantum Coherence and Computing held in Napoli, Italy,
in June 2000. This workshop gathered a number of experts from the
major Universities and Research Institutions of several countries.
The choice of the location, which recognizes the role and the
traditions of Naples in this field, guaranteed the participants a
stimulating atmosphere. The aim of the workshop has been to report
on the recent theoretical and experimental results on the
macroscopic quantum coherence of macroscopic systems. Particular
attention was devoted to Josephson devices. The correlation with
other atomic and molecular systems, exhibiting a macroscopic
quantum behaviour, was also discussed. The seminars provided both
historical overview and recent theoretical ground on the topic, as
well as information on new experimental results relative to the
quantum computing area. The first workshop on this topic, held in
Napoli in 1998, has been ennobled by important reports on
observations of Macroscopic Quantum Coherence in mesoscopic
systems. The current workshop proposed, among many stimulating
results, the first observations of Macroscopic Quantum Coherence
between macroscopically distinct fluxoid states in rf SQUIDs, 20
years after the Leggett's proposal to experimentally test the
quantum behavior of macroscopic systems. Reports on observations of
quantum behaviour in molecular and magnetic systems, small
Josephson devices, quantum dots have also been particularly
stimulating in view of the realization of several possible q-bits.
