We present a very general quantum-like model of lottery selection based on representation
of beliefs of an agent by pure quantum states. Subjective probabilities are mathematically …

It is well known that in quantum mechanics we cannot always define consistently properties
that are context independent. Many approaches exist to describe contextual properties, such …

In this paper, we examined the connection between quantum systems' indistinguishability
and signed (or negative) probabilities. We do so by first introducing a measure-theoretic …

We introduce nebit, a classical bit with a signed probability distribution. We study its
properties and basic transformations that can be applied to it. Then, we introduce a simple …

In this work, we discuss a formal way of dealing with the properties of contextual systems.
Our approach is to assume that properties describing the same physical quantity, but …

Derivation and experimental violation of Bell-like inequalities involve the measurement of
incompatible observables. Simple complementarity forbids the existence of such joint …

This paper addresses the theories of Fractional Calculus and Negative Probabilities. The
fundamental concepts are discussed and a number of analogies are established between …

In this chapter, we present a general theory of finite quantum measurements, for which we
assume that the state space of the measured system is a finite dimensional Hilbert space …

Since the experimental observation of the violation of the Bell-CHSH inequalities, much has
been said about the non-local and contextual character of the underlying system. However …

We provide an analysis of complementarity via a suitably designed classical model that
leads to a set of inequalities that can be tested by means of unsharp measurements. We …
