# Quantum Probability: a reliable tool for an agent or a reliable source of reality?

## TL;DR

This paper explores different interpretations of quantum probability, proposing an objectivist view that sees it as revealing an intensive reality, and discusses its implications for quantum computation and logic.

## Contribution

It introduces an objectivist interpretation of quantum probability based on the Born rule and examines its potential benefits for quantum computational models.

## Key findings

- Proposes an objectivist interpretation grounded in the idea of an intensive realm of reality.
- Analyzes the limitations of subjectivist interpretations in quantum computation.
- Suggests advantages of the intensive account for modeling quantum computation.

## Abstract

In this paper we attempt to analyze the concept of quantum probability within quantum computation and quantum computational logic. While the subjectivist interpretation of quantum probability explains it as a reliable predictive tool for an agent in order to compute measurement outcomes, the objectivist interpretation understands quantum probability as providing reliable information of a real state of affairs. After discussing these different viewpoints we propose a particular objectivist interpretation grounded on the idea that the Born rule provides information about an intensive realm of reality. We then turn our attention to the way in which the subjectivist interpretation of probability is presently applied within both quantum computation and quantum computational logic. Taking as a standpoint our proposed intensive account of quantum probability we discuss the possibilities and advantages it might open for the modeling and development of both quantum computation and quantum computational logic.
