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

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.

Automated summary

This paper examines the concept of quantum probability within quantum computation and logic, discussing both subjectivist and objectivist interpretations. It proposes an objectivist interpretation based on the idea that the Born rule provides information about an intensive realm of reality, and explores the implications for modeling and development in quantum computation and quantum computational logic.
