November 2003 - July 2004 , Pavia

We will have a workshop of 9 months, starting from November 2003 and ending July 2004, with small working groups of researchers visiting the QUIT Group at Pavia. Each visitor/working group will stay for a period of time varying from a few days to two weeks, with a few exceptional longer visits of a month. Few visitors will be also invited to teach two-week mini-courses on topics of the workshop.

Funding is available to cover expenses or to pay short contracts, from our Italian grant (MIUR) and from ESF. Different funds are regulated by different rules (see bureaucracy tips). ESF is sponsoring the workshop under the QIT program, and their support is available for participants from the countries supporting the program.

The workshop will be interdisciplinary, grouping physicists, mathematicians, statisticians and computer scientists, also with the objective of developing a common language and bridging cultural gaps between the different disciplines.

A starting list of visitors with visiting dates is available in the following, it will be regularly updated, and will work as a condensation point for the groups of visitors. Visiting of young scientists will be encouraged. Also, external proposals to join existing groups or to start new groups will be considered, depending on availability of funds and local logistics.

Advisory Scientific Committee

Giacomo Mauro D'Ariano, Martin Plenio, Reinhard Werner, Vladimir Buzek, Michele Mosca.

Local Organizing Committee

Paolo Perinotti, Massimiliano Sacchi.


The main purpose is to develop general methods for engineering and testing devices for manipulation of quantum information, using transformations and measuring apparatuses available in the current technology. The topics that will form the core of the activity will be:
  1. Quantum theory of measurements:
    1. programmable quantum measuring devices;
    2. informationally complete measurements, mutual unbiased bases, nice error basis, universal detectors and tomographers;
  2. Quantum cryptography;
  3. Quantum error correction;
  4. Quantum Turing machines;
  5. Entanglement: theory and applications to measurements and communications;
  6. Quantum and classical capacity of channels;
  7. New algebraic approaches to quantum information processing.
