Dear Matthew,

I am afraid that the problem with the superposition may be harder. In fact, the superposition problem must be consider as a part of the problem of the which way information. The problem stays in the fact that the existence resp. not existence of the which way information can influence the real physical processes. The superposition…[Read more]

Dear Robert,

You have written “The consistent histories approach was initiated in order to deal with probabilities in the quantum context, and I think it has solved the problem–while I allow that there may be alternative or better approaches.”
I think that the consistent description of probabilities in quantum mechanics needs more. Probability a…[Read more]

Dear Robert,

You have written “Can quantum mechanics and special relativity be combined into a single coherent theory?” But this is neccesary !! The reality cannot be inconsistent !! The microworld is described by the quantum mechanics and the special relativity. Without the consistency of these two theories the quantum theory cannot exists. But…[Read more]

Dear Robert,

You have written “Is measurement essential to any formulation of quantum mechanics, or can measurements be described using fundamental quantum principles that make no reference to measurements?”. I comment that if measurement should be the part of the quantum theory, than you will need something as the concept of the observation.…[Read more]

Dear Robert,

You have writen “how shall we understand quantum correlations as in EPR-Bohm?”. This is the basic question. If any local quantum mechanics could be possible, it must at the first place to give the local explanation of the EPR correlations !! Of course, the first goal is to exclude the derivation of Bell inequality. But the local…[Read more]

Dear Carlo

Quantum theory is about the ensembles and about the individual outcomes of measuring systems. But I think that in quantum mechanics there are less real events than in clsxsical mechanics but there are more real events than in the classical statistical mechanics. The reason is the fact that quantum mechanics is reversible probabilistic…[Read more]

Dear Robert

thank You for Your mail

your comments were very inspiring for me

to the locality: I agree with You that QM must be local – in the sense that locality must be among axioms. Then possible derivation of Bell inequalities (BI) gives the inconsistency of QM. Thus for me the problém is how to make local QM consistent. I have red your…[Read more]

The most pressing problem of Quantum Theory is to find a consistent modification of Quantum Mechanics (QM) satisfying the following conditions
(i) in the modified QM the derivation of Bell inequalities is not possible
(ii) in the modified QM the locality is an axiom
(iii) experimental consequences of the modified QM are the same as experimental…[Read more]
