We provide a self-contained introduction to quantum theory using a unique diagrammatic
language. Far from simple visual aids, the diagrams we use are mathematical objects in …

The paper presents quantum model of subjective text perception based on binary cognitive
distinctions corresponding to words of natural language. The result of perception is quantum …

We provide a general description of the phenomenon of entanglement in bipartite systems,
as it manifests in micro and macro physical systems, as well as in human cognitive …

Parallelism represents an essential aspect of human mind/brain activities. One can
recognize some common features between psychological parallelism and the characteristic …

Immersive learning environments in education provide a set of rich and diverse learning
affordances (possibilities). Cognition in such environments can be considered as embodied …

Quantum computational logics represent a logical abstraction from the circuit-theory in
quantum computation. In these logics formulas are supposed to denote pieces of quantum …

By using the abstract structures investigated in the first Part of this article, we develop a
semantics for an epistemic language, which expresses sentences like “Alice knows that Bob …

Some critical open problems of epistemic logics can be investigated in the framework of a
quantum computational approach. The basic idea is to interpret sentences like “Alice knows …

Quantum computation and quantum computational logics are intrinsically connected with
some puzzling epistemic problems. In the framework of a quantum computational approach …

Quantum information gives rise to some puzzling epistemic problems that can be
interestingly investigated from a logical point of view. A characteristic example is …
