### [Fis] Reply to Eriksson Zenith: Unification of QI and CI?

nonlocality, you could proceed with such an interpretation. There is nothing wrong, since the mathematical apparatus is correct in any way! With Best Regards, Andrei Khrennikov Director of International Center for Mathematical Modeling in Physics, Engineering, Economy and Cognitive Sc., University

### [Fis] QI and probabilities: reply to Michel Petitjean

Dear Michael, The question on the difference between classical and quantum probabilities is really fundamental for QI. The situation is not so simple as it was described in the Email below. Yes, I agree that if we consider one fixed experimental arrangement then we obtain the usual

### [Fis] Noncommuting observables: reply to Srinandan Dasmahapatra

Dear Srinandan, Your question about teh difference in statistical data for commuting and noncommuting observables is extremely important for probabilistic foundations of QM. First I recall my and yours points: On 20-May-06, at 11:13 AM, Andrei Khrennikov wrote: the real problem

Sampling Assumption in EPR-Bell Experiments] The main problem for me: to find such a dependence of statistics on experimental settings in other domains of science. May be somebody could come with some ideas? With Best Regards, Andrei Khrennikov Director of International Center for Mathematical

### [Fis] Reply to Jakulin:Can quantum probabilities be always reduced to joint probabilities?

A and B; P(A=-1,B=+1|o(A),o(B))= 1/2 sin^2 (a-b)/2, and so on. We tokk this answer from QM. But you would not be able to find a single probability distribution for A,B,C. Therefore I speak about contextual probability theory. With Best Regards, Andrei Khrennikov Director of International Center

### [Fis] Reply to Ted Goranson: Quantum Gravity

fundamental theory is purely classical and QM is just an approximation of such a theory. So the postulate on the completeness of QM is not so innocent, it is not just a philosophic subject... With Best Regards, Andrei Khrennikov Director of International Center for Mathematical Modeling in Physics

### Re: [Fis] Quantum Information - Probability Functions and Information

Dear Steven, I was not able to reply you earlier. But I think that I should do this even so late after your Email. You posted problems which are very important (at least for me). 1. Quantum probability functions are either directly equivalent to probability functions in Shannon\'s

### Re: [Fis] Probability Amplitudes

Dear Joseph, you are going toward quantum probability theory where probabilities are determined by vectors; moreover, the vectors belong to complex Hilbert space, i.e., roughly speaking each probability has not only the direction but even the phase, andrei Andrei Khrennikov, Professor

Dear Marcus, I would ask for clarification on whether you speak of information in your examples as something that has innate meaning or something that is innately meaningless . . . which has been a core issue in earlier exchanges. If this issue of meaning versus meaningless in
