  This preprint contains a detailed Preface to Proceedinngs of the
International Conference ``Foundations of Probability and Physics-3'' held in
V\"axj\"o, Sweden, 7-12 June 2004; table of contents and round table. The main
theme of the round table was {\it ``Fundamental problems in quantum mechanics,
probabilistic description of reality, and quantum information.''} The topics
that were specifically discussed were that of Quantum Cryptography, Quantum
computing, and Quantum Macroscopic Structures. For each of these topics, the
participants were asked to discuss which are the crucial Quantum features
required among the following : violation of Bell's inequality, Entanglement,
Complementarity, and Interference of Probabilities. Finally, the connection
between Mental states and Quantum states was discussed.
