Workshop on: QUANTUM MEASUREMENTS AND OPERATIONS FOR CRYPTOGRAPHY AND INFORMATION PROCESSING

October 2004 - October 2005 , Pavia

We will have a workshop of 10 months, starting from October 2004 and ending July 2005, 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 local expenses [no travel] or to pay short contracts, from our Italian grant (MIUR). Different funds are regulated by different rules (see bureaucracy tips).

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, ...

Local Organizing Committee

Paolo Perinotti, Massimiliano Sacchi.

Topics

The main purpose is to develop general methods for engineering new quantum measurements and quantum operations for application to Quantum cryptography and to Processing of Quantum Information. The workshop will also cross-fertilizatize current researches on Foundations on Quantum Mechanics and Quantum Measurements. The topics that will form the core of the activity will be:
  1. Foundations and Quantum theory of Measurements and Open Systems:
    1. Programmability of Measurements and Quantum Operations;
    2. Convex Structures of Channels, Measurements, and States;
    3. Ultra-sensitive Measurements;
  2. Applications:
    1. Quantum Cryptography;
    2. Applications of Entanglement to Measurements, Communications, and Quantum Processing ;
    3. Quantum and Classical Capacity of Channels;
  3. Algebraic Approaches and Group-Theoretical Methods;
  4. Quantum Turing machines;
