Abstract. In quantum computational logics meanings of sentences are identified with quantum information quantities: systems of qubits or, more generally, mixtures of systems of qubits. We consider two kinds of quantum computational semantics: 1) a compositional semantics, where the meaning of a compound sentence is determined by the meanings of its parts; 2) a holistic semantics, which makes essential use of the characteristic “holistic ” features of the quantum-theoretic formalism. The compositional and the holistic semantics turn out to characterize the same logic. In this framework, one can introduce the notion of quantum-classical truth table, which corresponds to the most natural way for a quantum computer to calculate classical tautologies. Quantum computational logics can be applied to investigate differ-ent kinds of semantic phenomena where holistic, contextual and gestaltic patterns play an essential role (from natural languages to musical com
