An indeterminacy-based ontology for quantum theory

I present and defend a new ontology for quantum theories (or "interpretations" of quantum theory) called Generative Quantum Theory (GQT). The ontology assumes that the world can be fundamentally indeterminate in the sense of being constituted by entities with indeterminate properties. The process via which determinate values arise and persist differs in different quantum theories. I will focus on the following quantum theories: GRW, the Many-Worlds Interpretation and single-world relationalist theories, Bohmian Mechanics, hybrid classical-quantum theories, and Environmental Determinacy-based (EnD) Quantum Theory. Moreover, quantum states represent quantum properties and structures that give rise to determinacy, and each quantum theory specifies a structure with specific features. I will argue that GQT should be taken seriously because it provides a series of benefits that current influential ontologies lack, namely, wavefunction realism and primitive ontology, without some of their costs. Furthermore, it allows for the formulation of quantum theories that are clearly compatible with relativistic causality, such as EnD Quantum Theory. Finally, I will show how GQT provides a new way to compare and evaluate different quantum theories.
