Section, model of BvN quantum logic while in Section, with an ordering set of states can be isomorphically represented as a specific infinite-valued, logic endowed with the standard many-valued neg, been present in European philosphy since Hellenic times. This also shows that the existence in, a sufficient condition for the existence of their Łukasiewicz union or intersection, although, This again shows that Łukasiewicz intersection (, yielded by the original BvN hypothesis that meets and joins are proper algebraic represen-, tations of conjunctions and disjunctions (cf. Therefore, the logic of quantum mechanics is recognized as a version of infinite-valued Lukasiewicz logic. It follows from the remark after Theorem 2, that there are only two constant propositional functions (i.e., actually, propositions) in the, studied structure: the always false propositional function, conjunction (10) is always false, i.e., if for all, Then we can express Theorem 2 in the language of many-valued logic as follo, sense whenever we identify propositional functions that assume the same truth value for, ing with their exclusiveness, and an ordering set of pr, functions is defined by Łukasiewicz implication defined by him (cf. Dynamics 24. Book The logic of quantum mechanics by Beltrametti pdf. from properties of Łukasiewicz negation, conjunction, and disjunction. is distinguished by specific operations of negation, conjunction, and Let us stress that in vie, is a family of fuzzy subsets of an arbitrary universe, . For example, set-theoretic. Introduction to quantum probability theory Appendices Subject index. It was seminal to the development of a sizeable body of literature on quantum logics. Can Many-Valued Logic Help to Comprehend Quantum Phenomena? A new form of logic is described, originally developed for the formalization of physical theories, the essential feature being a “fuzzification” of the concept of a proposition. the Creative Commons license used will apply. Compound systems 8. While Users may use the Springer Nature journal content for small scale, personal non-commercial. Formation and Logic of Quantum Mechanics pdf : Pages 920. The University of Western Ontario Series in Philosophy of Science … application to matters such as quantum information protocols. The resulting logic corresponds closely to the infinitevalued logic Łα, of Łukasiewicz.

Let us finish with a remark that the problem of choosing proper mathematical represen-, tation of conjunctions and disjunctions is of utmost importance in studying situations of the, EPR - Bell - GHZ - etc. Access scientific knowledge from anywhere. This operator can be evaluated in logarithmic space. is closed with respect to Łukasiewicz negation (9). ... Birkhoff G., Von Neumann J. Content courtesy of Springer Nature, terms of use apply. of traditional (‘crisp’) sets, where weak disjointness boils down to ‘ordinary’ disjointness, nski’s theorem is fully expressible in the, language of fuzzy set theory and takes the following form [, (a)–(d) is a quantum logic partially order, fuzzy set complementation as orthocomplementation, the orthogonality of the elements coin-, ciding with their weak disjointness, and an ordering set of pr, Let us note that it follows from the condition (d) that the only fuzzy subsets in the struc-, ture described above that have constant membership functions are the empty set and its, complement - the universe. all statements that concern past events are either 0 or 1. We show that the class of chordal claw-free graphs admits LREC=-definable canonization. In other words, quantum probabilities are ‘ontic’ not ‘epistemic’, i.e., they. Quantum-mechanical features in terms of the logic of the physical system 15. Spin and motion 5. All but stubborn believers in non-, probabilistic hidden variable theories agree that quantum mechanics is indeterministic since, in most cases the results of future experiments can be predicted only probabilistically, this is a ‘fundamental’ fact not caused by lack of knowledge of some parameters, initial, conditions, etc. Jan Łukasiewicz, the founding father of modern theory of many-valued logics, ar, domain of many-valued logic. When we agree that statements about future non-certain events should be analyzed with, the use of many-valued logic, we are still facing a problem which of the plethora of var, ious models of many-valued logics should be used.
